【摘要】 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。更多还原

【Abstract】 On May 12th,2008,an earthquake of magnitude 8 occurred in Wenchuan county,Sichuan province,which subsequently caused many landslides among the Long MenShan 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: the instantaneously sliding stage;the intensive colliding-air cushion effect stage;the scraping slow down stage;the deposit state.更多还原
