Abstract

[This study aims to simulate the flow-like landslides which caused by the Wenchuan earthquake 2008. For approaching this phenomenon, it is difficult to examine for simulation method based on continuum model that occurred in landslide body due to collision of granular materials and its effect. In this paper, we modeled this phenomenon as multi-phase flow, and simulated by discrete element method (DEM) and simplified maker and cell method (SMAC) with introducing simplified interaction. As for the verification of simulation especially for interaction, terminal settling velocity test is executed and shows quantitatively agreement. Moreover, through this simulation, moving process of the Tangjiashan landslides picked up as typical flow-like landslides. This landslide located beside the valley, and due to the landslides it held the mountain stream. Based on this simulation, depositional process is obtained.]
