摘　　要：2008年汶川地震触发了大量滑坡,引起堵江事件多达两百余起,严重威胁着地震灾区居民的生命财产安全,进一步加剧了地震灾害。为此,讨论地震滑坡堵江机理以及堰塞坝的溃坝模式,并采用水力学、极限平衡理论以及渗流力学等方法,研究了堰塞坝的溃坝机理及条件。2008 Wenchun Earthquake triggered a large number of landslides, and then caused over 200 landslide dams, seriously threatening the safety of life and property of the local residents and further intensifying the earthquake disasters. The mechanism of seismic landslide dam and the modes of barrier dam break were hereto discussed and, by means of applied hydraulics, limit equilibrium theory and permeation fluid mechanics, the mechanism and conditions of barrier dam break were studied.
