Evaluation of Soil Reinforcement Potential of Grass Variety

Gobinath Ravindran, G. P. Ganapathy

Abstract


Reinforcement potential of plant root is studied by many researches across the globe. This work aims to analyze the effect of grass root in the improvement of engineering properties of soil. Plant roots being a natural material help in enhancing the shear strength of soil. Field and laboratory studies were conducted on a grass variety (Co-4) and the soil reinforcement potential of the plant is studied. It is found that the root zone enhances the shrinkage characteristics of soil, reduces the consolidation, and increases the shear strength and density. The effect on specific gravity, saturation ratio is insignificant but the liquid and plastic limit is increased.
