In this paper, simulation analysis for shearing mechanism of rock joint by Distinct Element Method is performed. The purpose of this study is to analyze the sliding and shearing behavior of discontinuity surface in the shear process and destruction locations of the roughness is tried to be clarified by numerical simulation. The characterization of this simulation model can be applied on bonding force between particles. As the results of this study, it is recognized that the shearing and sliding behavior of discontinuous plane using this simulation model correspond with the experimental results and that this simulation model are useful. The distribution of internal stress during shear on discontinuity plane can be visualized.
