2003年7月13日,三峡水库初期蓄水至135m高程30d之际,在三峡库区秭归县发生了三峡库区的第一个水库滑坡,滑坡方量达1500万m3,最大滑速达16m/s,最高涌浪达24.5m。滑坡造成10人死亡,14人失踪,摧毁129间民房以及4个工厂,致1200人无家可归。千将坪滑坡发生后,为了预测三峡库区及世界其它水库工程可能发生的同类高速滑坡,持续数年研究千将坪滑坡的高速滑动机制,通过理论分析及数值模拟,探索了千将坪滑坡的高速滑动机制,认为千将坪滑坡具有孕育高速滑坡的典型结构特征,滑坡滑带的峰残强降差是滑坡高速启动的根本原因,高陡边坡蕴藏的高势能及滑带液化是滑坡加速高速滑动的主要原因。
On July 13, 2003, at the beginning of impoundment of the Three Gorges Reservoir to an elevation of 135m for 30 days, the first reservoir slide in the Three Gorges reservoir area occurred in Zigui County of the Three Gorges Reservoir. The landslide volume reached 15 million m3 and the maximum slip rate reached 16m / s, the highest wave of up to 24.5m. Ten people were killed and 14 were missing, landslide destroyed 129 houses and 4 factories, leaving 1,200 people homeless. After Qianliangping landslide occurs, in order to predict similar high-speed landslide likely to occur in the Three Gorges reservoir area and other reservoir projects in the world, the high-speed sliding mechanism of Qianqoping Landslide has been studied for several years. By theoretical analysis and numerical simulation, It is considered that the Qianjiangping landslide has the typical structural features of high-speed landslide. The peak-residual difference of the landslide is the root cause of the high-speed landslide. The high potential energy and the liquefaction of the landslide are the landslide Speed up the main reason for high-speed sliding.
