摘要
On May 12th, 2008, an earthquake of magnitude 8 occurred in Wenchuan County, Sichuan Province, which subsequently caused many landslides among the Longmenshan central fault seismic zone. On the basis of the investigation, this paper uses the discrete element method through 2D-block software to analyse the mechanism of the Xiejiadianzi landslide-rockflow. The results are presented below: 1) the instantaneously sliding stage; 2) the intensive colliding-air cushion effect stage; 3) the scraping slow down stage; and 4) the deposit state.
