Due to strong ground motion of earthquake, the debris sliding at high velocity can travel a distance several times longer than the height of the slope. It is suggested that the energy is transported from slope to debris mass by the collisions occurred during earthquake. In order to simulation this unexpected motion process with DDA, the displacement accuracy of DDA applied to collision is investigated in this paper. With appropriately estimated contact resistance force, it shows that the behavior of the system trends toward the analytic solution and the resulting precision is sufficient. Finally, a comparison of behavior under collision between DDA and DEM is discussed based on the simulation results.
