ABSTRACT
Numerical modeling tools are used due to its several advantages over the conventional limit equilibrium method (Griffiths & Lane1999; Duncan 1996). Griffiths & Lane (1999) summarized the results of a slope stability analysis using finite element method(FEM) based on shear-strength reduction technique and provided information concerned to the advantage and disadvantage of FEM for the use in a practical slope engineering problem. The discrete element method (DEM) was introduced by Cundall & Strack (1979) explained the mechanical behavior of assemblies of discs and spheres. However, precise block geometry and more understanding is required to get a realistic and reliable simulation for jointed rockmass.
