Static analysis of Mansa Devi hill landslide using FLAC3D

摘要

The present study mainly deals with the analysis of Mansa Devi landslide, Haridwar, Uttarakhand,rnIndia. The area experiences local as well as regional slides every year. The experimental work were conducted torndetermine the various mechanical property of rock mass. These properties have been used as input parametersrnfor the numerical simulation of slope using FLAC3D. The deformations in all the three direction and stressesrnalong xx and zz axis as in these direction movement take place have been calculated. Finally factor of safety ofrnstudy area is calculated. The study indicates that slope at the higher height along the slope is unstable and it isrnstable at the lower height. The effects of instability have been thoroughly considered.
