Abstract

This paper deals with slope stability evolutions by limit equilibrium (LE) methods and compared with the results from GEOSLOPE software. The LE based methods are compared based on the factor of safety (FOS) obtained from various conditions with simplified slope geometry and assumed input parameters. The Bishop simplified Method (BSM) and Janbu simplified Method (JSM) is compared with Morgenstern?Price method (M?PM) and it is seen that the prediction of the most critical slip surface is influenced by the search technique. The comparative study among the LE methods showed that BSM is as good as M?PM for normal condition in circular shear surface (CSS) analysis whereas simplified Janbu (JSM) method gives the most conservative value of the FOS.
