Abstract


 

This study addresses a temporary shoring system design used in the construction of an urban road corridor in four areas, with a total length of about 93 m and excavation heights of 5.2 m and 8.5 m. A comparison was made between the original design and a present study. The first condition was calculated manually following Brazilian standards, while the last one was made through computational programs, following the recommendations of German standards. Also, the present study uses more reliable geotechnical parameters, based on results of triaxial compression tests on undisturbed samples, while in the original design the soil parameters were adopted from SPT correlations. Even considering a more severe external loading in the present study than the original design, the computed efforts obtained in this last condition were higher, being more discrepant in the shoring with 8.5 m height. In the original design, the embedded length were 47% and 79% higher for the 8.5 m shoring and 60% for the 5.2 m shoring, when compared to the current study. Also, normal efforts in the struts reached a difference of almost 100%, for the higher shoring, but, with close values, in the lower shoring. The maximum horizontal deflections in the soldier-piles were close for the 8.5 m shoring. All the computed parameters satisfied the condition of structural stability, however, the horizontal deflections in the timber planks were superior to the admissible for the shoring of 5.2 m, both in the original project and in the present study. The overall stability of the soil-soldier-pile system was higher than the minimum of the Brazilian standard, in the current study condition, since such verification had not been carried out in the original design.
