This paper uses DDA to simulate the movement of three large landslides triggered by the Wenchuan earthquake. The simulated and actual deposits corresponded well only when the apparent friction coefficient, which was obtained by field investigation, was used rather than the friction coefficient measured in the laboratory. Furthermore, two cases, in which initial horizontal velocities of 0 and 1 m/s respectively were assigned to the failed mass, were analyzed to clarify the effect of earthquake energy on deposit. The results show that the initial horizontal velocity had very small influence on the simulated deposits.
