Discrete Element Method For Slope Stability Analysis

A static DEM has been presented to solve slope stability analyses. The method consists ofrndiscretizing the soil mass into blocks which are joined by Winkler springs. From relation ofrnforces with stiffness and displacement, sets of simultaneous equations are solved to findrndisplacements and stresses. The local stresses are used to calculate factor of safety while therndisplacement fields are used for predicting the critical failure surface.rnExample problems have been solved using DEM and the results have shown the potential ofrnthe method for slope stability analysis. Comparisons of the present model between limitrnequilibrium methods, FEM and with DEM models by other authors are made .The resultsrnsuggest that DEM methods can be used both to predict the critical slip surface and give arnfactor of safety and that these outputs closely agree with the conventional limit equilibriumrnmethods and the more rigorous FEMs.
