ABSTRACT

Predicting the stability of the rock slopes has always been a challenging problem for civil and mining engineers while dealing with dams, roads, tunnels, opencast mines, etc. The performance of rock slopes subjected to seismic action can be evaluated through seismic coefficient of safety and permanent displacement. The majority of existing methods depending on the fundamental approach adopted in each method fall into three categories: finite element methods (FEM), forcebased pseudo-static methods, and displacement-based sliding block methods (Cai, 1996). The FEM is one of the most comprehensive approaches to implement a through analysis of performance of soil structures induced by seismic loading. However, a reliable result from FEM is dependent on accurate measurement and interpretation of soil properties which is usually difficult to achieve. So the application of FEM is confined.
