Slope Stability Analysis Using Numerical Modelling

Abstract

Stability analysis of slopes is a very important component of various opencast mining projects throughout the life cycle of the project. A failure of slope in the area being worked in a mine can lead to some severe social, economic as well as a great safety catastrophe. The basic failure conditions are very diverse & complicated. These failure mechanisms are greatly dependent on local geology, which are pretty unique to a specific location of the rock mass. In the recent years too, the method of designing slopes are completely based upon the field knowledge. Better approach can be made through safe designing of slopes. The aim of the project is to carry out numerical modelling for slopes having various dimensions and different rock properties. The numerical modelling is carried out using FLAC SLOPE for finding out the factor of safety. The parameters are varied for each slope and the factor of safety calculated for each step. These values are correlated with the bench parameters to find out how the factor of safety changes with changing parameters.
