APPLICATION OF LIMIT ANALYSIS TO THE SLOPE STABILITY PROBLEM

Abstract

This thesis aims to evaluating the stability of slopes using Limit analysis (LA) method and compare it to Finite Element Analysis (FEA) and conventional methods of analysis. Mohr-Coulomb soil model is used in the numerical modeling using assumed values of soil strength parameters to cover a wide range of different soil types. In this thesis, a series of numerical models are carried out using SLIDE software for Limit equilibrium (LE) analysis, slope stability charts based on LE methods for seepage analysis and Optum G2 with plane strain conditions for FEA and LA. Different cases of analysis are modeled regarding soil types, soil strength parameters and water head in the slope. The results are discussed and summarized regarding factor of safety.
