2008年5月12日14时28分,四川省汶川县发生8级特大地震。此次地震触发的高速远程滑坡—碎屑流主要沿龙门山主中央断裂地震破裂带展布。本文在现场调查分析的基础上,使用2D-block离散元软件对地震引发的谢家店子滑坡—碎屑流运动规律进行了全程数值模拟分析。通过现场调查和模拟结果对比分析,将该滑坡的运动规律概括为4个过程:剧动启程抛掷;快速撞击—气垫飞行;铲刮减速碎屑流;堆积掩埋。 At 14:28 on May 12, 2008, a magnitude 8 earthquake hit Wenchuan County in Sichuan Province. The high-speed remote landslide-debris flow triggered by the earthquake was mainly distributed along the rupture zone of the main central fault of the Longmen Shan. Based on the field investigation and analysis, this paper uses 2D-block discrete element software to simulate the whole process of the earthquake-induced Xie Jiandian landslide-debris flow movement. Through the comparative analysis of field survey and simulation results, the law of motion of the landslide is summarized into four processes: drastic throwing; rapid impact - air cushion flight; scraping decelerating debris flow;
