Abstract

Black cotton soil is a problematic soil in the field of construction due to its poor shear behavior. The main objective of this study is to analyze the shear parameters of reinforced black cotton soil numerically using SIGMA/W in the Geo Studio tool. The study has been carried out to investigate the shear parameters of considered soil for different layers of reinforcement. The necessary boundary conditions have been applied for the numerical model. The numerical analysis has been performed considering various stresses and forces such as deviatoric stress, vertical stress, confining stress, and backpressure. The result in terms of effective stress, major principal stress, minor principal stress, total stress, and pore water pressure is obtained. The results obtained from numerical simulation are compared with those of the experimental studies of black cotton soil. This study shows that the results are within the marginal limits.
