In recent years, the numerical modeling methods have extensively applied instead of limit equilibrium methods. Also, the probabilistic methods are considered in rock slope designs to quantify the uncertainties involved in the slope stability problem. In this paper, a probabilistic-numerical approach is proposed, which is based on integration of three dimensional Distinct Element Method (DEM) and probabilistic approach for stability analysis of rock slopes. Barton models were used to model the behavior of rock discontinuities and the shear strain was considered as failure indicator of discontinuities. The proposed methodology .
