Abstract: The shear strength of jointed rock masses is determined by the structural surface and the adjacent intact rock shear strength; When the structural surface is completely connected, the shear strength of rock mass is determined entirely by the structural surface. Monte Carlo method can simulate the spatial distribution of the discontinuity in jointed rock masses according to the geometry parameters of the structural surface; and then the connected structural surface can be searched via depth-first algorithm; and compared with the rock mass, the shear strength of the connected structural surface is the smallest; so it can be considered as the potential sliding surface of jointed rock slope. The stability of a series of sliding surfaces can be analysed by the limit equilibrium method. This method is the complement of the jointed rock slope stability analysis.

Key words: jointed rock masses, dominant orientation of structural surface, sliding surface, Monte Carlo method, depth-first algorithm, limit equilibrium method
