An Analysis of Ujjani Reservoir in Solapur, Maharashtra, India, Using Mathematical Modeling and Satellite Remote Sensing Techniques for Sedimentation Studies
type: item
description: The reservoir's storage capacity steadily decreases due to sedimentation. The reservoir life can be preserved by monitoring sedimentation and implementing appropriate management measures. The Ujjani dam was built for power generating, irrigation, and water delivery systems. It is located in the drought-prone Solapur district, due to which Ujjani is an important initiative for the region's economy and society. In the present study, the Ujjani reservoir's sedimentation is evaluated for monitoring purposes. In order to estimate sedimentation, two methods are used in present study: mathematical modeling with HEC RAS and the Satellite Remote Sensing Technique (SRST). The Satellite Remote Sensing technique is gaining popularity over traditional hydrographic surveys due to advantages such as cheap cost, time savings, reduced labor requirements, accuracy in estimation, and the possibility to carry out previous surveys. ARC-GIS software was used to identify the water spread areas at various reservoir levels based on satellite pictures of Ujjani Reservoir. We used the prismoidal formula to compute the volume between two water levels. The original volume of the reservoir during impoundment was compared to the current volume of the reservoir. This demonstrated the volume loss brought on by sedimentation. With the development of new computer technology, engineers may now use computer simulations and modeling to solve hydraulic problems and sediment transport equations. By utilizing the ever-increasing processing power, numerical modeling has not only shortened computation times but also enhanced the process of testing the impacts of various input variable sets. For Ujjani Reservoir, a mathematical model was created using the HEC RAS program. Sediment volume change profiles were obtained by running this sediment model for quasi-unsteady flow.There is a fair degree of consistency between the sedimentation volumes determined by the two approaches. Additionally, a comparison is made…

description: This research has presented a sophisticated methodology for studying lithosphere-ionosphere coupling phenomena, emphasising the identification of pre-seismic activity through seismo-electromagnetic signal processing. The application of an advanced electric field monitoring device, coupled with the precision of the Discrete Wavelet Transform (DWT), has allowed us to uncover nuanced patterns in the ULF range, specifically related to seismic events during the Kumamoto Earthquakes. The detailed statistical analysis further supports the significance of our findings, providing a quantitative measure of variance for each detail level. The capability of our methodology to extract abnormal signals associated with various earthquake preparation stages is a promising step forward in earthquake research. This innovative approach holds great potential for advancing our understanding of lithosphere-ionosphere coupling and its role in early seismic activity detection. The findings contribute to the broader field of seismo-electromagnetic research, demonstrating the importance of sophisticated signal processing techniques in extracting meaningful information from complex datasets. Future research endeavours and validation studies can build upon this foundation, potentially enhancing the applicability of these techniques in earthquake prediction and monitoring systems.

Machine Learning Approach for Analysis of Ionosphere Parameters for Earthquake Precursors
type: item
description: This research explores the relationship between seismic events and predictive indicators, focusing on machine learning-based strategies for early earthquake prediction. It dissects existing prediction approaches, highlighting ionospheric anomalies' correlation with seismic occurrences, particularly preceding earthquakes of magnitudes higher than 5.5. By identifying a lack of comprehensive long-term analyses in the field, the study emphasizes future trends in machine learning-driven EQ-PD techniques using GPS-TEC data for real-time anomaly detection. The methodology involves seismic hazard monitoring in Turkish coal mines, leveraging specialized equipment and diverse machine-learning algorithms for enhanced prediction accuracy. The study's core involves analyzing seismic wave datasets alongside real-time ionospheric data to evaluate the EQ-PD approach. Utilizing FFT seismic wave analysis, precursor detection, and machine learning-based classification, this research underscores the EQ-PD technique's potential for early earthquake prediction. The findings present a robust framework amalgamating seismic wave analysis, ionospheric anomaly detection, and machine learning, offering promise for practical application in mitigating earthquake impacts.

type: item
description: This research work is mainly focused on analysis of geotechnical aspects/parametres of Sheet Pile embedded in any soil condition using Finite Element Analysis. For this research work the finite element geotechnical analysis package Optum G2 has been brought into use. The Soil and Sheet Pile both have been designed/modelled as per Mohr-Coulomb Criterion. Here strutted(braced) sheet pile system using a strut modelled as fixed end anchor C300 (with yield force = 300 kN/m). The strutted sheet pile has been assessed for in presence of pseudo-static seismic loading Thereafter resultant parametres similar or different are illustrated, via modelling of 2D elements on Optum G2 . Using limit analysis with embedded depth of sheet pile being 0.4 and 0.5 times of total height of sheet pile i.e. 3.6m and 4.5m, the load multiplier value came up as 5.19 for both values of embedded depth of sheet pile. The Cantilever Sheet Pile is under induced strip loading. Thereafter resultant parametres similar or different are illustrated for it, via modelling of 2D elements on Optum G2. On this sheet pile Multiplier Elastoplastic analysis has been performed, under four different values of prompted strip load (q) of 35, 49, 56 and 70 kN/m2 . A 2Y-X graph has been made exhibiting variation of displacement ϴ and total displacement |u| of sheet pile with increase in height of structs from bottom of finite soil section. Variation of ϴ with height seems to be S-shaped curve while variation of |u| with height a rough J-shaped curve.

Experimental Analysis on Improving the Soil Characteristics by Stabilization of Black Cotton Soil Using Coir or Coconut Fibre
type: item
description: One of the most widely utilized methods for improving poor soils is soil reinforcement. Metal strips, natural and synthetic fibers arranged randomly, geogrid sheets, synthetic and natural geotextiles, and metal strips are examples of materials used for soil reinforcement. Additionally, the tensile strength, shear strength, other characteristics, bearing capacity, and economy are all significantly improved by the soil reinforcement. The utilization of jute fibre in civil engineering is beneficial for enhancing soil qualities due to its affordability, accessibility, biodegradability, and environmental friendliness. The objective of this experiment is to explore the influence of varying percentages—0.25%, 0.50%, 1.0%, 2.0%, and 3.0%—of jute fiber reinforcement on the CBR (California Bearing Ratio) qualities of soil. The findings of the tests reveal a consistent augmentation in the CBR characteristics of soil with the increasing presence of fiber. Moreover, a direct correlation was observed between the rise in fiber content and the corresponding increase in the CBR value of the reinforced soil. This discernible enhancement in CBR values, particularly in soil reinforced with jute fiber, serves as substantial evidence of a significant alteration in engineering behavior. For this investigation, a total of five soil samples, both with and without reinforcement, were meticulously prepared at their respective maximum dry densities, maintaining ideal moisture content within the CBR mold. Subsequent laboratory analysis yielded CBR values for both unsoaked soil and soil reinforced with jute fiber. The results unequivocally demonstrate a positive correlation between the increase in fiber content and the subsequent rise in CBR value of the soil. Additionally, it was shown that the CBR value of reinforced soil improves significantly with the length of the fiber increases, reaching a range of 1.5% to 2.0%. The thickness of pavement subgrade can be significantly reduced, and construc…

type: item
description: The exploration and utilization of natural resources demand a skilled workforce equipped with a strong foundation in engineering and geoscientific knowledge, complemented by technical expertise. Engineers and geoscientists play a crucial role in the forefront of these endeavors, benefiting from their relevant knowledge and proficiency. This comprehensive overview of applied geology underscores the importance of essential skills required for the identification and description of prevalent rock-forming minerals. These minerals play a fundamental role in the intricate processes of rock formation. By acquiring and honing these vital skills, professionals in the field can effectively contribute to the successful exploration and characterization of geological resources. Thus, applied geology also encompasses earth processes, generally known as geohazards, particularly earthquakes, which negatively affect the progress already achieved. Hence, geologists must study those processes and recommend mitigation measures that are necessary for minimizing damage in geological terrains that are vulnerable to the geohazards.

Predicting the Influence of Permeability’s on Settlement of Shallow Foundation
type: item
description: Foundation settlement rose as soil permeability increased, excess pore pressure increased with depth, and decreased as shear modulus increased. The expanding soil cycle (shrinkage and expansion) that is principally responsible for foundation settlement is strongly related to water content. The application of modeling and simulation was used to monitor the effect of various soil properties on foundation settlement. But the focus of this study is on Permeability including other soil properties like moisture content; water content, these were also investigated. The variations in soil permeability on settlements reflect on the soil lithology, and the foundation settlement of soil on different depth developed influence on the soil's stability, thus reflecting on the bearing capacity. The study observed heterogeneous soil deposition as it reflected on soil properties and foundation settlement influence, the study explained the heterogeneous impacts of permeability, moisture content, void ratios, and ground water as it affect settlement condition of silty clay deposition, the application of modeling and simulation with experimental techniques has generated some significant factors that affect soil foundation settlements in different dimensions. The trend experienced linear growth rate in all the graphical representation under numerical simulation, these simulation concept were able to monitor the rate of permeability numerically within the depth of 0.1-1.6m, the simulation data were compared with the measured values, the study is imperative because it has explained the impact of settlement rise due to permeability increase in heterogeneous deposition, these reflect the increase of excess water pressure. It has also expressed the influence of shrinkage and expansion as it reflects to settlement from water content impact.

Advancing the Strength of Expansive Soil using BioEnzyme and Pond-Ash
type: item
description: Expansive soils are problematic and prone to ground movements, which can seriously harm underlying structures and reduce their carrying ability. The expansive nature of soils is activated by moisture fluctuations, causing it to expand and contract. There are many stabilizing chemicals that have been used to treat Black Cotton soil, including lime, cement, and fly ash. Recently, it has become clear that using bio-enzymes to stabilize soil has a lot of potential. The effectiveness of enzymatic stabilization of expanding soils in road pavements is examined in this paper. To establish the permanency of stabilized soil, many experiments were performed. The application of an enzyme-based stabilizer showed its ability to maintain material stiffness despite changes in moisture, considerably increasing the strength of soils. In this study, the effects of combining Black Cotton soil that has been stabilized with Roadzyme and Pond Ash are examined throughout a range of curing times. The soil's Unconfined Compressive Strength (UCC) and California Bearing Ratio (CBR) readings were shown to be significantly improved over time using Roadzyme.

A Comparative Study on Contaminated and Uncontaminated Soils Surrounding the Municipal Wastes Disposal Site
type: item
description: Increase in population and industrialization has been creating space problems in and around the cities for habitation. In addition, the cities have been facing disposal problems of solid and liquid wastes generated from industrial and residential areas. Disposal of municipal solid wastes without planned way in any city has been causing air, water and soil pollution in the vicinity of dump site. The wastes disposal can alter the engineering properties of the soil. In this study, to compare the geotechnical properties of contaminated and uncontaminated soils, a municipal solid wastes disposal site of Khurram Nagar, Lucknow, Uttar Pradesh was selected. At this site, the municipal authority vehicles dump the domestic wastes, collected from door to door of the residential areas of Khurram Nagar. Soil samples (contaminated) were collected from all the four directions of the disposal site. The uncontaminated (raw soil) soil was collected nearby the dump site where there was no chance of flow of dump runoff. Then samples were analyzed for different geotechnical properties like moisture content, bulk density, consistency limits, compaction characteristics, particle size, etc. In addition, pH values of all the soils were also found out. The gradation of the particles was assessed based on the coefficient of uniformity and coefficient of curvature. Geotechnical properties of contaminated and uncontaminated soils varied from location to location. Keywords: Municipal solid wastes, contaminated, uncontaminated, consistency limits, particle size, compaction characteristics.

An Evaluative Analysis of the Utilization of Artificial Neural Networks in Forecasting Soil Engineering Characteristics: An Overview Study
type: item
description: The primary objective of utilizing synthetic neural networks was to emulate the problem-solving approach akin to the human brain. This approach of employing artificial neural networks gained extensive traction within the realm of geotechnical engineering, where the engineering properties of soil play a pivotal role in ensuring the stability of various engineering structures. The primary concern revolves around the strength and deformation characteristics exhibited by soil masses. The focus lies predominantly on attributes that gauge the responsive behavior of soils under varying conditions. This review paper presents a succinct overview of the applications of Artificial Neural Networks (ANNs) in accurately predicting crucial engineering properties of soil. These properties encompass essential factors such as optimal moisture content, maximum dry density, permeability, shear strength parameters, and unconfined compressive strength. The comprehensive assessment suggests that ANNs, employing diverse models, exhibit a remarkable degree of accuracy in forecasting the engineering properties of soil. The review also underscores the ANNs' capacity to effectively manage incomplete input data, rendering them notably advantageous in such scenarios. This study is poised to provide substantial assistance to researchers immersed in exploring the realm of ANN applications within the context of soil behavior analysis.

Behaviour of Micropiles Groups Subjected to Vertical Loads
type: item
description: Micropiles are used to reinforce soils and to support foundations. It may be installed in several directions through existing foundations so as to increase the bearing capacity of the soil and to reduce the settlement. The group effects of micropile groups subjected to vertical loads in granular soils have been investigated by many research workers. However the findings have been found to be inconsistent indicating contradictory group effects. Group behaviour of vertical micropiles groups subjected to vertical loads have been investigated in this study through model testing performed in sand consisting of different relative density. This behaviour is found to be a function of relative density of the sand, slenderness (L/D) ratio, spacing and number of piles in the pile group. The ultimate resistance increases with L/D ratio and with number of piles in the pile group. Ultimate resistance is maximum at 4D spacing in loose sand and medium dense sand at a relative density of 30% and 50%. Ultimate resistance is maximum at 2D spacing and minimum at 6D spacing in dense sand at a relative density of 80%. Efficiency of micropile groups is found to be a function of L/D ratio, density of the sand, the number of piles and spacing of the pile group. Correlations have been developed between the ultimate load and the various parameters involved.

Farming on Phone: Understanding Cotton Farmers’ Intentions and Feasibility to Adopt ICT-based Agro Advisory Services in Maharashtra, India
type: item
description: The use of ICT tools in the agriculture sector for rural farmers has emerged as a potential for empowering farmers and improving their livelihoods as the phone-based agro-advisory services provide farmers with access to tailored relevant information to help them make better decisions about agricultural activities, crop yields, and better management of natural resources. However, understanding the impact of social structure on ICT adoption and perceived impacts is important to ensure the viability of digital agriculture and optimal interaction between farmers, consumers, extension agents, and other value chain stakeholders. This study sought to ascertain the adoption and feasibility of the Cotton Doctor application introduced by WWF-India in view of curbing cotton production challenges in the Jalna district of Maharashtra through the administration of a tested questionnaire to participating farmers. A set of independent variables that include the sociodemographic profile of farmers that were thought to influence their willingness to use the app were surveyed. This study uses thematic and descriptive research design to understand the respondents’ perspectives on the application. The data collected was analysed using SPSS by calculating descriptive statistics (mean, percentages and frequencies) and inferential statistics (Fisher’s T test, Mann-Whitney U test and Kruskal-Wallis test). According to the results, except for the farmers’ experience in farming, there was no statistically significant relationship between the socio-economic characteristics of farmers and their use of the app, which indicates farmers were using the cotton doctor app regardless of their socioeconomic status. The findings showed that the majority of the farmers who responded considered information on weather forecasts and pest/disease management, followed by a daily advisory on farming activities, as being of foremost relevance. Despite the perceived benefits, the study identified a few considera…

Analysis of Geological Structure for the Application of Geotechnical Engineering to Optimize Thermal Extraction in Geothermal Wells
type: item
description: The characterization of the geological terrain for geothermal applications from the heat transfer point of view has been made. Horizontal, vertical and inclined geological layers have been analyzed. Uniform and homogeneous terrain are better candidates for low or high enthalpy geothermal applications while heterogeneous soil have a poorer performance from the thermal transfer point of view. The characterization process of soil structure and properties allows to take the appropriate decision on the type of heat exchanger for low enthalpy geothermal applications, either horizontal or vertical ducts distribution, and the suitability of any depending on the available surface. The study provides a criteria based on the characterization process to select the most adequate configuration of the heat exchanger for an optimum performance of thermal energy extraction from the geothermal bed. Likewise, thermal performance has been evaluated as a function of temperature drop in the heat carrier fluid as a consequence of non-uniform geological structure. An analytical method has been designed and developed resulting in an algorithm that allows the user to determine the temperature drop in the fluid as a function of known parameters. Performance of thermal extraction from geothermal wells improves as fluid diffusivity increases or thickness of different geological layers diminishes. The theoretical analysis of the problem has been applied to horizontal geological layer structure with the heat exchanger passing through vertically, but can also be applied to any configuration like inclined or vertical layers and perpendicular or obliquus heat exchanger position.

Assessing the Impact of Soil-Structure Interaction on Seismic Performance of Step Back and Set Back Buildings on Sloping Ground
type: item
description: When constructing framed structures on sloping ground, either step back or step back and set back configurations are typically adopted. Due to the varying heights of columns towards the slope and the unsymmetrical nature of these buildings, they are subject to large forces such as shear forces, bending moments, torsional moments, and unequal distribution. In the past, it was common practice to assume that structures were fixed at the base, which can lead to errors in evaluation during dynamic loading, particularly depending on the type of soil at the base. To more accurately capture the real behavior of reinforced concrete (R.C.C.) framed buildings resting on a slope, this study uses response spectrum analysis to examine the effect of soil-structure interaction (SSI) on the seismic performance of R.C.C. framed buildings with varying underlying soil types (hard, medium, and soft soil) and angles of slope from 10 to 40 degrees using ETABS software. The buildings will also be analyzed with respect to various slopes of ground and soil types, incorporating shear walls. Results will be analyzed in the form of base shear, bending moment, torsional moment, time period, storey displacement, and storey drift.

Application of High Speed Videography and Digital Image Processing Software to Assess Performance of Blasts In Opencast Mines: A Case Study
type: item
description: Rock mass can be fragmented by the process of blasting in which a known volume of the yield is obtained by using a calculated quantity of explosive. The explosive selected for blasting depends on factors like rock mass parameters, blasting economics and blast design. Assessment of the performance of a given blast is essential in the larger economics of the mining project. A study was conducted to know the blast performance at two different mines. High speed videography was used to assess blast performance and wastage of gaseous energy. With the increase in stemming height from 1.0m to 3.5m, it was found that there is decrease in the escape of gas energy ejection from 7.42m height to 3.5m, which was almost half the height of ejection. The analysis showed that the maximum velocity of rock movement was found to be 8.97m/s in Mine-A and 12.40m/s in Mine-B with varying strength of intact rock mass. Wipfrag digital image processing software was used to determine the fragment size distribution, which gives quick and accurate measurements. Blast-4 of Mine-A with explosive charge of about 33.36kg/hole produced finer fragmentation compared to Blast-4 in Mine-B with same explosive charge, clearly showing influence of strength of rock mass.

type: item
description: The present document is the first paper of a serial of studies ongoing in geotechnical laboratory testing and in situ testing of marine sediments in the southern Italy coastal area. For this first stage, Undrained triaxial compression tests with anisotropic consolidation (CK0U) have been performed on marine sediments collected in boreholes carried out in the seabed, in a depth of 8 m to 18 m below the seabed. The use of this compression test allows: (i) to consolidate the specimens, under the application of vertical load, limiting lateral strain and without reaching failure; (ii) the evaluate the entity of the maximum axial strain in the aforementioned conditions; (iii) to measure, during the entire cutting phase, the pore pressure values. The purpose of this paper is to highlight the first set of results from this particular triaxial compression test. The representation of the results by means of stress paths, allow to identify distinctly the breaking point of the specimens, defining with extreme precision the limit of the shear strength and cohesion of the soil without resorting to Mohr’s circles. Keywords: Marine sediments, Undrained triaxial test, Anisotropic consolidation.

Effects of granulated waste glass and micro steel fiber on shear strength parameters of sand
type: item
description: During the construction of the various structures, soil strength plays a vital role in structural performance. Hence, soil improvement techniques are needed to improve soil strength as well. This study aimed to improve shear strength of sandy soil using Granulated waste glass (GWG) and Micro steel fiber (MSF). In order to apply this idea, there have been taken two kinds of sandy soil such as fine sand (locally available in Kushtia) and coarse sand (locally available in Domar). As for basic properties of sand, fineness modulus, specific gravity, maximum dry density, etc. are determined from experimental results. After grounding the waste glasses into granulated form and cutting the 0.70 mm steel wire into a uniform size of 10 mm in length, the GWG and MSF have been mixed in the sand by various proportions namely 5%, 10% and 15% by weight. The observation on the soil improvement technique which is adopted in this paper is summarized that the cohesion of the Kushtia sand is increased up to 1376.7% for 10% MSF and angle of internal friction is increased up to 8.7% for 10% GWG. The cohesion of the Domar sand is increased up to 1877.5% for 10% MSF and angle of internal friction is increased up to 24.4% for 15% MSF. Therefore, it can be concluded that the shear strength becomes increase for both sand up to optimum content using the considered percentage of GWG and/or MSF.

Simplified Analytical and Numerical Analysis for Stability of Tunnel and Foundation Containing Sloping Ground
type: item
description: Tunnel, foundation and superstructure effect on the stability of slope. Numerical and simplified analytical analyses evaluate behavior of slope under various conditions. However, factor of safety indicates failure criteria of slope. Present research develops some simplified analytical formulae for a specific model and numerical code (PLAXIS 3D) performs finite element analysis of this model. During numerical analysis considers Mohr-Coulomb material model and drained condition. Factor of safety assesses from variations of sloping angles (30°, 35° and 40°) and horizontal distances (0 m, 1 m, 2 m, 3 m, 4 m, 5 m and 6 m) between sloping face and tunnel as well as foundation face. Numerical and analytical results match at zero horizontal distance for each angle of slope. Angle of failure surface varies 27.7, 28.6 and 28.3 percentages of 30°, 35° and 40° slopping angles respectively based on analytical analysis. Little difference between analytical and numerical results of some locations expresses accuracy of newly developed simplified formulae.

Potential of Limestone Powder in the Production of Self Compacting Concrete
type: item
description: Self-compacting concrete (SCC) is a cutting-edge building material. It's a smooth, durable concrete that fills the formwork completely. The SCC needs a lot of powder to perform well (mostly cement). However, increasing the cement content is impractical and may result in greater hydration heat and drying shrinkage. This project studies the effect of limestone powder (LSP) on the fresh and hardened appearances of SCC. To evaluate the samples with and without LSP as a partial replacement for cement, a control sample of concrete was generated. There were four mixes created using superplasticizer, sand, coarse aggregate, and water at varied replacement amounts of 0, 10, 20, and 30% from cement weight. The results show that replacing up to 30% of the cement in SCC with limestone powder increases the workability of fresh concrete. Conversely, compressive strength increases from 30.35 N/mm2 to 33.73 N/mm2 and 36.26 N/mm2 as the proportion of limestone powder grows from 0% to 10% and 20%, but drops from 36.26 N/mm2 to 21.27 N/mm2 as the percentage of limestone powder increases from 0% to 10% and 20%, respectively (20 percent to 30 percent). Calculated water absorption data show that 10% to 20% replacement reduced average water absorption from 9.54 to 8.87 percent, while 30% replacement reduced average water absorption from 9.54 to 8.87 percent. The water absorption % increased from 8.87 to 9.46. These studies suggest that up to 20% of the cement in SCC can be replaced with limestone powder.

Steepening Pit Walls- Geotechnical and Economic Implications
type: item
description: Current approach to pit-wall analysis tends to separate designs into distinct categories. The first consideration involves analysis of slope in which discontinuities actively participate in the failure mobilization. The second involves design analysis of non-structural controls which could results in a wide range of failure mechanisms. The third and the least sought for approach is the economic assessment of the slope design which could render optimized pit slope and the bench face angle scenarios economic or otherwise. The sensitivity of the third consideration has become imperative in the face of depleting pit reserves as any positive turn over in the economic analysis could revive distress mine operations. A typical operating pit sited west of Ghana’s metalogenic province which was near collapse due to ore depletion was re-designed through steepening of the slopes to expose more resource. Geotechnical, window and photogrammetry mappings were carried to augment the historical data available. Several numerical analytical tools were also employed to model the pitwall angles. Four steeper slopes were designed from the current BFA of 65° to 70°, 75°, 80° and 85o. This was done to assist in stability, reduce stripping ratio and improve cash flow. The results indicated that discontinuities steeply oriented towards east direction could make the slope highly susceptible to planer and toppling failures The studies concluded that it may not be feasible to steepen BFA from the current base angle due to the predicted steeper angles as a results of overall slope instabilities even though the potential economic benefit is substantial. If steepening would be considered, major modifications of slope geometry; rock improvement, extensive slope monitoring and a good groundwater control management mechanisms may be required.

Some Geomechanical and Petrophysical Linkages Within Paleo-Sedimentary Beds of Ghana
type: item
description: Instability issues have been a major challenge in the Sekondian Series of South-Western Ghana. This is particularly affecting civil works and environmental mitigation efforts across the formation as extensive weathered profile impedes structural integrity. Uniaxial Compressive Strength (UCS) of lithological units which is a critical stability measure in most engineering projects requires quality sample of appropriate dimension for its determination. Samples for this important design parameter cannot be easily obtained from the Sekondian sedimentary strata, except at deeper depth, requiring extensive drilling. However, the parameter could be inferred from other properties of the rockmass.This research examines some geomechanical and petrophysical properties of the EfiaNkwanta beds by correlation and regression analysis to obtain models for stability inference. The models were established with the t-test and F-test using Minitab programming. The analysis was performed on disaggregated samples from the beds. The test methods employed were UCS, porosity, saturation and particle density. Correlation interpretation was based on Correlation Coefficients and P-value whereas regression analysis was based on R-square, the P-value and Residual standard deviation. The results indicated that linear association existed between the UCS and Porosity within the sandstone of well sorted grains and connected pores. Thus, the compressive strength of the sandstone was found to be dependent on the degree of pore connectivity. The EfiaNkwanta sandstone gave the best linear correlation with the rest showing appreciable dependence.

Soil Reinforcement Using Waste Plastic Materials
type: item
description: Soil reinforcement is a ground improvement techniques used in different civil engineering structures like earth retaining structures, embankment, foundations, road construction, etc.In this study, an attempt was made to collect the soil samples in such a way that it has different plasticity index. Accordingly, samples from surrounding areas of the Kanpur were collected and analyzed for their plasticity index. It was observed that three locations such as PSIT Campus, Naramau and Bithoor indicated medium plastic, high plastic and low plastic category of soil respectively. Hence these soils were used for soil reinforcement study. Waste plastics like polythene bags and plastic bottles cut into uniform small pieces of 1 cm x 1 cm size and made perforated. Then it was mixed in differentproportions like 0.50%, 0.75%, 1.00% and 1.25% with soils. The natural soils of different plasticity indexes were analyzed for optimum water content, maximum dry density, liquid limit, plastic limit, particle size, shear strength parameters (angle of shearing resistance, cohesion) and California bearing ratio. Mixed proportions were analyzed for shear strength parameters and California bearing ratio. Influence of waste plastics on shear strength parameters and California bearing ratio were assessed. Influence of angle of shearing resistance on bearing capacity factors were also determined. Mixing of waste plastics with different types of soil improved the shear strength parameters and California bearing ratio.

Object Reconstruction Using Phone and Compact Camera
type: item
description: Previously, a 3D model can be produced by using high resolution and metric camera in close range photogrammetry technique. In this study, there were two types of camera used; the compact camera (Nikon COOLPIX L120) and phone camera (Samsung Galaxy Note1). Two objects were selected; i.e., a biscuit container as for simulation and water tank as the real object. 3D models for both objects were validated by using a measuring tape and laser distance. The 3D models were analysed based on a calculation of Root Mean Square Error (RMSE) and standard deviation. The RMSE for Galaxy note1 (GN1) was 0.870 cm with standard deviation ± 0.886 cm. On the other hand, RMSE for Nikon COOLPIX L120 was 0.757 cm with standard deviation ± 0.766 cm. The results showed that sub-centimetre level was achieved for both cameras in the water tank 3D models documentation.

Properties of Bentonite Stabilised with Fluorogypsum
type: item
description: This paper presents the properties of the bentonite stabilised with fluorogypsum. For this purpose, commercially available bentonite and fluorogypsum were used in this investigation. The fluorogypsum content and the curing period were varied from 0% to 10 % and 0 to 28 days respectively. Compaction tests results reveal that the maximum dry unit weight increases and optimum moisture content decreases with the increase in the fluorogypsum content to the bentonite. Further, 2 % fluorogypsum content in bentonite is effective in reducing the liquid limit of the bentonite drastically. However, effect of fluorogypsum on the reduction in the plastic limit of the bentonite is comparatively low. The liquidity index decreases with the increase in fluorogypsum content in the bentonite while as it increases with the increase in the curing period. The axial stress at peak as well as strain at failure increased with the increase in the fluorogypsum content added to the bentonite as well as the curing period. The axial stress at peak as well as strain at failure increased with the increase in the moisture content from OMC-3% to OMC+3%. Water content on the wet-side of optimum moisture content i.e. OMC+3% were effective in producing best results. The SEM-EDAX studies have demonstrated the development of cementation compounds by adding fluorogypsum to the bentonite. Such compounds were responsible for the improvement in the axial stress at failure with the increase in the curing period.

type: item
description: The strength parameters of saw dust ash on the geotechnical properties of lateritic soil for road construction purposes in Ghana have been investigated. The lateritic soil sample collected was subjected to the following test; Atterberg limits, compaction and California Bearing Ratio Test. The tests were conducted in accordance with BS: 1377 and AASHTO M145 standards. A varying percentage of the saw dust ash in order of 2%, 4%, 6%, 8% and 10% were mixed with the lateritic soil. The influence of the ash content on the Atterberg limits, compaction and California Bearing Ratio were investigated. The plasticity index of the lateritic soil reduced from 17.9% to 16.8% at 12% addition of the saw dust ash. The maximum dry density (MDD) reduced from 2.09Mg/m3 to 1.90Mg/m3at 12% addition of the saw dust ash however, the optimum moisture content increased from 14.14% to 16.71% at 12% addition of the saw dust ash. The California Bearing Ratio value increased from 59% to 74% at 10% addition of the saw dust ash. From a trend analysis, it was indicated that, there was a significant linear relationship between saw dust ash, California Bearing Ratio and the optimum moistures. Natural soils with high moistures were not investigated in this study.

Soft Computing Based Prediction of Ultimate Bearing Capacity of Footings Resting on Rock Masses
type: item
description: The present study attempts to predict the ultimate bearing capacity of shallow foundations on rock masses using five different soft computing techniques namely i) random forest regression approach, ii) artificial neural networks, iii) support vector machine with polykernel, iv) support vector machine with (radial basis function) RBF kernel and v) M5P model tree. The ultimate bearing capacity was assumed to be dependent rock mass rating, unconfined compressive strength of rock, ratio of joint spacing to foundation width, and angle of internal friction for the rock mass. The performance of each model was analyzed by comparing the statistical performance measure parameters. The outcome of present study suggests that support vector machine (SVM) RBF kernel predicts the bearing capacity with least error followed by random forest regression model. All the model predictions further outperformed those based on empirical approach available in literature. Finally, sensitivity analysis performed for the SVM RBF kernel model suggests that the unconfined compressive strength of rock was an important parameter, in comparison to other parameters, considered for predicting the ultimate bearing capacity.

Neural network based prediction of shear wave velocity for soils
type: item
description: The paper presents a study on the prediction of the shear wave velocity (Vs) for all soils using ANN model from cone penetration test data. The input parameters in the obtained of ANN models were vertical effective stress, sleeve friction, cone tip resistance and output was the shear wave velocity. These parameters were considered to construct the ANN model which has 3-2-1 topology in prediction of shear wave velocity. Further, utilizing the RMSE, MAE, MSE, MAPE, determination coefficient (R2) and correlation coefficient (r) for training and testing data set, performance of artificial neural networks was investigate utilizing different activation function. The created ANN model had an adequate precision. The contribution of input parameters on prediction of shear wave velocity was determined by sensitivity analysis and it is found that the contribution of vertical effective stress was 84% on the output shear wave velocity. It was much more as compared to other parameters. Therefore, the ANN model having topology of 3-2-1 was better as compared to the one developed using multi linear regression analysis (MLRA) as well as previously reported correlations in literature to estimate the shear wave velocity. Finally, an equation was proposed for the ANN model based on trained of weights and biases obtained.

A STYDY ON MECHANICAL PROPERTIES UNDER THE INFLUENCE OF FELDSPAR ACTIVATOR ON GEOPOLYMERIZATION OF REDMUD AND GGBS
type: item
description: It is well known fact that the Ordinary Portland Cement (OPC) is most important construction material. Keeping in view the hazardous effects of Portland cement on environment, efforts are being put to reduce use of cement in concrete with its partial or full replacement by various waste materials such as Red mud (RM), Ground Granulated Blas Furnace Slag (GGBFS or GGBS), Flyash, Silica fume etc.. Geopolymer Concrete (GPC) is a result of such effort. Geopolymerization mechanism involves the reaction between various materials rich in silica and alumina such as RM and GGBS etc. in the presence of alkaline medium to form a binder which binds the aggregates and the other unreacted materials together to form a complex and strong system called Geopolymer Concrete. An experimental study was conducted to arrive at an optimum mix proportion for GPC and thus to study its mechanical propertiesviz., compressive strength, split tensile strength and flexural strength. This investigation also involves the study of elemental composition of GPC and its composite materials.

Solid Waste Management of Beta-1
type: item
description: With rapid urbanization, the situation is becoming critical. The urban population has grown fivefold in the last six periods with 285.35 million people living in urban areas as per the 2001 census. Waste is littered all over leading to insanitary living conditions. Municipal laws overriding the urban local bodies do not have adequate provisions to deal effectively with the ever-growing problem of solid waste management. Solid waste management is one among the basic essential services provided by municipal authorities in the country to keep urban centre clean. However, it is among the most poorly purified services in the basket. The structures applied are unscientific, outdated, and inefficient; population coverage is low; and the poor are marginalized. This paper covers the solid waste management strategies in Beta-1 area.

Optimization of Compressive Strength of Segmental Interlocking Stones
type: item
description: The failure of most segmental interlocking stones used as pavement materials is traceable to lack of knowledge of the mix ratios that would optimize the compressive strength of the end products. In this study, the compressive strength was optimized based on Scheffe’s simplex lattice approach. The reliability of model developed was investigated using F-statistic and was found to be adequate. A computer program written in basic language was used to predict with reasonable accuracy, the mix ratios corresponding to a desired compressive strength value that fell within the experimental domain. The mix ratio that optimized the compressive strength was found to be 1:2 (cement: coarse sand), corresponding to a water-cement ratio of 0.526.

Taguchis Parameter Design Approach to normal cement concrete mixture proportioning
type: item
description: This paper presents the results of the optimization of normal cement concrete mixture using Taguchi approach. The Taguchi experiments were designed using an L9 orthogonal array with three factors and three levels each. The water-cement ratio (W/C), total aggregate-cement ratio (TA/C) and total aggregate-water ratio (TA/W) were treated as the control factors. The effects of the water-cement ratio, total aggregate-cement ratio and total aggregate-water ratio on the compressive strength were analyzed using signal–to–noise ratios (S/N) and mean response values of the compressive strength of normal cement concrete. The compressive strength was maximized at water-cement ratio of 0.395, total aggregate-cement ratio of 3.795 and total aggregate-water ratio of 9.81 respectively. The mean value of the compressive strength at the optimum settings was 29.32N/mm2 with a tolerance value of ± 4.35Nmm2. A validation test was carried out to investigate the mean value of the compressive strength at the obtained values of optimum settings and was found to be 25N/mm2 which fell within the range of the predicted optimum. The optimization model was tested for adequacy using a normal probability plot and the residuals were found to almost fall on a straight line showing that the errors followed normal distribution. It was also revealed that the water-cement ratio contributed more to the compressive strength followed by total aggregate-cement ratio and then the total aggregate-water ratio.

A New Model for Prediction of Wellbore Stability Using the Three Dimensional Hoek–Brown Failure Criterion
type: item
description: Wellbore stability is one of the crucial issues in oil and gas industries. The issues related to instability of wells, impose significant unwanted costs on drilling operation.The objective of this paper is to present the 3D-wellbore stability prediction models for vertical wellbores. The three dimensional Hoek–Brown strength criterion developed by Zhang and Zhu conjunction with linear poroelastic constitutive model is utilized to develop the models. This models leads to easily computed expression for the critical mud pressure required to maintain wellbore stability. The analytical model is applied to real field case in order to verify the applicability of the developed models.The results indicate that the decreasing of the Biot’s coefficient and increasing the UCS and/or Poisson’s ratio will increase the optimum mud pressure window. Furthermore, this window is a function of depth.

A Review of Geophysical, Geochemical and Geotechnical Study of the Marine Soil of Mahakalapada With Special Allusion to Its Stratigraphic Set-up
type: item
description: The present study deals with the marine soil properties collected from Mahakalapada of Kendrapara district in Odisha. Five numbers of saturated soil samples were collected from 2ʹ to 3ʹ below the earth surface and were mixed thoroughly to get the best result. The soil was initially air dried in open atmosphere prior to the testing. The various properties of each sample was calculated either in-situ or in the laboratory. The average value for all the samples is considered for further analysis. The geology of the study area was studied carefully before determining grain size distribution; sieve analysis followed by hydrometer test of the samples. The stratigraphic set up of the area indicates that the sedimentation took place during Oligocene-recent period and was mostly clastic in nature and extends like a blanket. The marine sediments were deposited under the marine and progressive environmental conditions whose thickness increases from west to east. The soil samples were black colored, fine grained and highly plastic in nature with specific gravity ranging from 2.07 to 2.65. Moisture content is 128.94%.

The Environmental Impact of Soil Pollution on Human Health
type: item
description: Soils are shaped by the decomposition of rock and organic matter over several years. Soil properties vary from place to place with difference in bedrock composition, climate and other factors. Certain chemical elements occur naturally in soils as components of minerals, yet may be toxic at some concentration. Various other potentially harmful substance may end up mixing with soils through human activities. This may lead to soil contamination which in turn is responsible for negative health effects on humans. Soil contaminants causes various health problems from cancer (arsenic, asbestos, dioxins), to neurological damage and lower IQ (lead, arsenic), kidney disease (lead, mercury. cadmium). Mainly heavy metals and persistent organic chemical are of particular concern. Human activities introduce heavy metals to soil through mining, smelting, industry, agriculture and burning fossil fuels.

Prediction and Assessment of Lateral Displacement of Rock Mass Along the Length of the Horseshoe Cavern – A Numerical Modelling Approach
type: item
description: The stability of the underground structures is a key to successful underground mining. Caverns are large underground openings constructed in rock mass for a variety of purposes. The properties of intact rock mass are generally overshadowed by the properties of discontinuities, if the discontinuities are present. Mechanisms of deformation and failure of underground openings in jointed rock mass are determined by the characteristics of the geometrical distribution of discontinuities. This paper presents stability studies of a horseshoe cavern carried out using 3-Dimensional Distinct Element Code (3DEC). The horseshoe cavern has been created in a granitic formation which has a rock mass rating (RMR) value 65. Discontinuities were invoked into the model in the form of horizontal joint set, horizontal and vertical joint sets, horizontal and oblique joint sets and horizontal, vertical and oblique joint sets. Behaviour of the cavern was analysed under varied conditions, in terms of deformations at different locations in the cavern. Comparative analysis was carried out to find the relation between the horizontal displacements at all specified points for the models having intact rock mass as well as discontinuities using distinct element method.

Soil Stabilization with Waste Shredded Rubber Tyre Chips
type: item
description: Soil stabilization means modification of the soil properties by the addition of any other material to meet the required engineering requirements. Construction engineering structures on the weak soils are considered to be unsafe. The load bearing capacity of these weak soils can be improved by means of various ground improvement techniques. Use of waste shredded rubber tyre chips in geotechnical engineering for enhancing the soil properties has received great attention in the recent years. In the present investigation, waste shredded rubber tyre chips have been used as the reinforcement material. 2% cement as binding agent, which was randomly included into the soil at different percentages of waste shredded rubber tyre chips content of 0%, 5% and 10% by weight of soil. The samples were subjected to California bearing ratio (soaked and unsoaked) tests. The tests have clearly shown a significant improvement in the shear strength and bearing capacity parameters of the soil. The results obtained are compared with unreinforced samples and inferences are drawn towards the usability and effectiveness of shredded rubber reinforcement as a replacement for deep or raft foundation and on pavement subgrade soil as a cost effective approach. The low strength and high compressible soft clayey soils were found to be improved by addition of waste shredded rubber tyre chips and cement. It can be concluded that waste shredded rubber tyre chips can be considered as a good earth reinforcement material based on laboratory results on limited tests.

Development of Attenuation Relationships for Underground Blasts: Different Equations
type: item
description: Blasting operation becomes essential for excavation in weathered and hard rock strata for construction and mining activities. The Indian Standard and industrial practice of establishing the site specific attenuation relationship recommend Power form of relationship between the PPV the scaled distance with an exponent of 2/3 (IS) and 1/2 (industrial practice). In this paper, three different equation forms and five different exponents were explored for modelling the aforementioned relationship for a particular site. It was concluded that the universally popular Power model was among the best models for the aforementioned relationship followed closely by the Reciprocal model and the Weibull model, the last suffering from parsimony. Further, it was found that exponents other than the popularly used 1/2 or the IS recommended 2/3 might give better results. The IS code was found to yield conservative values of safe charge weight for a particular safe PPV for a certain distance.

Research Insight on Everest Contaminated by Toxic Metals
type: item
description: The goal of this investigation of the Everest was to look at follow component fixations and altitudinal patterns in soil and snow. Mount Everest was chosen since its remote area and amazing height disengages it from limited contamination sources. Soil tests were gathered from Mount Everest by different specialists and the examples were broke down for Pb, Zn, Cd, Ni, Cr, Co, Cu, As, Mn, Hg, and V utilizing inductively coupled plasma spectroscopy. Comes about demonstrate that As and Cd are both above USEPA drinking water rules in all snow tests, and arsenic is over the USEPA soil screening rules in all dirt specimens. There was a reasonable pattern in component variety in the dirt examples, with the most elevated focuses found. There was no unmistakable pattern distinguished in the snow tests, perhaps because of vertical blending of surface snow. Anthropogenic sources are suspected to have added to the lifted groupings of both cadmium and arsenic. So this insight is about the dirt contamination on Mount Everest.

Spatial and Temporal Variation of Bioaerosols with Meteorology at Different Land Sites
type: item
description: Air particulates associated with biological origins are termed as bioaerosols. These bioaerosols consist of different species of bacteria, fungi, pollen and spores, etc. and can be allergenic and infectious in nature. The study is an attempt to understand the seasonal variation in bioaerosols concentration at three different land use sites: site I (commercial site), site II (dumping site), Site III (vegetated site). Statistical correlation was applied to infer the relation between bioaerosols concentration with meterological parameters (relative humidity and temperature) at selected sites. The study showed that Site II (dumping site) has high bioaerosols concentration (129 CFU) with high bacterial number (80 CFU) whereas the site III (vegetated site) has highest fungal concentration (67.8 CFU). This shows that different land use type and their micro habitat affect the type of biogenic agent that harbour. The bacterial and fungal concentration shows anti-synergistic trends with RH and temperature at different land use pattern. Contrastingly, at site II (dumping site) where the RH (42.5%) is observed to be minimum and are accompanied with maximum bacterial count.. Study demonstrates the strong correlation between temperature and abundance of bacteria indicated that temperature is one of the most important meteorological factors controlling bacterial abundance whereas the humidity exceeds the fungal population. In winter season the fungal concentration dominates the ambient environment whereas in summer season the bacterial spores were contributing most.

Effect of Varying Shear Velocity on the Mechanical Behavior of Jointed Rock Subjected To Lower Normal Load
type: item
description: : This study investigates the effect of shearing velocity on the mechanical behavior of rock joints, namely, the shear strength, residual strength, joint dilation, its surface roughness and the shearing stiffness under the application of lower normal load. The slower rate of shearing plays an important role in creep and the fatigue effect on jointed rock masses whereas, higher rate of shearing is experienced in the cases of dynamic loadings such as earthquake ground motion, blasting, drilling and traffic loading. In order to study the influence of shear velocity on the mechanical behavior of joints, CNL direct shear test are conducted at the geotechnical engineering laboratory of Kyoto University, Japan. The shear velocity effects the degree of interaction between the joint wall and the change in the surface roughness, which is brought upon by the asperity degradation during shearing. Finally, these phenomena will have the significant effect on the overall mechanical properties of the joint. However, under the lower normal load (< 1.00 MPa) shear velocity has no serious effect on the mechanical properties of the joint. Hence, based on the experimental results, its effect can be neglected for the normal confining stress less than 1.00 MPa. Eventually, the results of this work can help in studying the weak nature of jointed rock slopes under dynamic loading conditions which would be the main focus of this research work in near future.

Under Water Blasting for Rock Dredging & Protection of Structures: A Case Study
type: item
description: Rock dredging in ports involves under water blasting for the pretreatment of hard sea bed. A rock dredging project covering an area of about 257,058m2 involving 400,000 cu.m of hard Khondalite rock mass was taken up in a port in the east coast of Southern India, for deepening of Turning Circle and Inner Harbour Channel. Pre-blast survey was carried out to assess type and condition of various structures standing on different distances from the dredging area and safe Peak Particle Velocities (PPV) were assigned. STADDPro analysis was carried out for determining the natural frequency of some marine structures with pile foundation. Under water blasts were planned with varying blast configurations at different locations from the structures in order to maintain the vibration levels to within prescribed threshold values. In total, 1,150 under water blasts were conducted till date, consuming about 425t of explosives. Down the hole initiation was implemented for protecting nearby structures from blast vibrations. The paper gives details of the methodology of underwater blasting and related studies carried out.

A Case Study of the Krishna Bhir Slope Failure Disaster: Past and Present Scenario at a Glance
type: item
description: The massive landslide disaster of Krishna bhir has been infamous for its dreadful consequences. This huge landslide in the region led to serious socio-economic and environmental disorders in the vicinity of the region, whose negative impacts were reflected soon in the capital city. In addition to the feeble geology, the blasting and drilling activities, rampant deforestation, heavy monsoon rain and the poor drainage are the engenders for weakening the natural slope resulting the perpetual slope failure of Krishna bhir. The concept of bio-engineering cum civil engineering was implemented by the Department of Road – Nepal to strengthen the hill slope and manage the mass movement. This has been a very effective solution since, it has managed to sustain the slope from more than past decade. However, Krishna bhir has managed to revert to its volatile state once again. Hence, this study investigates about the past and the present condition of the slope with the future recommendations to prevent the impending landslide.

Application of Suitable Admixtures (Lime and RHA) for Improvement of Pavement Subgrade
type: item
description: Abstract The quality of a pavement depends on the strength of its sub-grade. The present investigation has been carried out with easily available materials like lime and rice husk ash mixed individually and in combinations with different proportions. The different percentages of lime with respect to weight of dry soil were 2%, 4%, 6%, 8% 10% and for rice husk ash (RHA) were 3%, 6%, 9% and 12%. In each case the stabilized soil was compacted at optimum moisture content (OMC). In each case California Bearing Ratio (CBR) tests and in case of compaction at OMC Unconfined Compressive Strength (UCS) tests were performed. The effect of curing on UCS samples upto 180 days with the intervals of 30 days was also studied. It was found that CBR of original soil improved from 4.25% to a maximum value 28.25% when mixed with combination of 6% lime and 9% rice husk ash (RHA) under unsoaked conditions and from 3.5% to 29.82% when mixed with a combination of 6% lime and 6% rice husk ash (RHA) with respect to dry weight of soil under soaked conditions at optimum moisture content (OMC). The unconfined compressive strength (UCS) of original soil was improved by 253% when mixed with 6% lime and 6% rice husk ash (RHA).However the maximum value of UCS is attained by a value of 285% when mix proportion of 4% lime and 9% rice husk ash. Based on the laboratory test results correlations have been developed between California Bearing Ratio (CBR) at optimum moisture contents as function of different soil parameters by multiple linear regression models. To gain an insight into the reasons of strength increase by identifying the microfabric structure of soil and soil-lime-RHA mixes, semi quantative analysis with X-ray diffraction (XRD) and X-ray fluorescence (XRF) were conducted. The interpretations of results of XRD and XRF tests have clearly indicated that change in strength between lime and rice husk ash admixture occur due to change in silica and mica contents. It is concluded from this study t…

Seismic Bearing Capacity of Strip Footing Subjected to Eccentric Load
type: item
description: Reinforced soil bed is improved soil strata from its weak unreinforced original form. By introducing reinforcing ties or strips the soil bed improves on its strength and is rendered less settleable. The compensations of introducing reinforcements have been widely studied by many researchers. The present work has evaluations, formulations and calculations for bearing capacity under certain seismic excitation when the strip footing on reinforced soil was subjected to eccentric loading. The contrast of bearing capacity of the footing when it is subjected to eccentric loading with that when subjected to uniform seismic loading and uniform vertical static loading has been done. The benefit of using layers of reinforcing ties in refining the seismic bearing capacity of the footing has been established.

Seismic Hazard Assessment of Dehradun City
type: item
description: Seismic hazard assessment refers to an estimation of ground motion parameters at any site or region. In the present study seismic hazard assessment is performed for the Dehradun city which lies in a highly seismic region in the Himalayan foothills. Based on the seismicity data provided by IMD, New Delhi and Seismotectonic Atlas of India (GSI, 2000), seismicity was described and 24 seismotectonic sources were identified in the study area. Assuming one third of the total fault length as rupture length for MCE, maximum magnitude to each source was assigned. After the estimation of distance of zone of energy release two different attenuation models were used to define peak horizontal acceleration based on shortest distance between sites and respective seismotectonic sources. The seismic hazard in terms of peak horizontal acceleration was estimated to be 0.334 g using attenuation model by Sharma (2000) and 0.475 g using attenuation model by Abrahamson and Lithehiser (1989). The computed peak horizontal acceleration in the present study is in confirmation with the observed values of Uttarkashi and Chamoli earthquakes and is also comparable to values reported in other studies.

Admixtures Effect on Consistency Limits and Shrinkage Characteristics of Expansive Soil
type: item
description: Effective usage of admixtures into the soil mixtures improves the characteristics of the soil for better construction. Particularly admixtures such as rice husk ash (RHA), quarry dust (QD) and flyash (FA) showed greater effect on the two types of expansive soils namely black cotton soil (BCS) and clayey soil. The percentage of admixtures is in the range of 0 to 30% at an interval of 10%. This study showed effective results in expansive soil along with the admixtures.
