摘　　要：基于剧冲式高速岩质滑坡几何学、运动学、动力学模型,通过离散单元法数值模拟,揭示和仿真再现了高陡边坡岩体破坏失稳后大变形阶段的运动过程和状态,进而为滑坡运动全过程动力学机理分析提供了科学依据。Based on the models of landslide geometry, kinematics and dynamics, and through a distinct element numerical simulation, the process and mechanism of slope rock mass moving and landslide damming in the big deformation stage after failure were revealed and reappeared, thus providing a scientific basis for the stability evaluation of landslide dam and the dynamic analysis of landslide damming by shock wave.
