 In view of Xiejiadianzi highspeed and long runout landslide caused by Wenchuan Earthquake, based on the investigation and analysis on the spot, a two-dimension discrete element numerical simulation model was built, numerical simulation was done by 2D-Block software. The results indicated that Xiejiadianzi landslide experienced four periods: the instantaneously sliding stage, the intensive colliding cushion stage, the scraping slow down stage and the deposit stage oft-com:office:office" />
