| 摘 要： | 千将坪滑坡是三峡一期蓄水后三峡库岸发生的最大体积滑坡,是典型的水库型岩质顺层高速滑坡.滑坡的地质结构、诱发过程与著名的瓦伊昂滑坡相似.其顺层主体连接缓倾角阻滑区的结构是孕育高速滑坡的典型结构.滑坡的主体运动方式是高速整体滑行运动,滑行过程中滑带有明显的液化现象.滑坡岩体的破碎情况对研究高速滑坡碎屑流启动部位有参考意义.

| Abstract: | Qianjiangping landslide,the maximum volume sliding after the first stage of water impounding in the Three Gorges Reservoir is a typical high-speed rocky-bedding slide,which is similar to the famous Vaiont landslide in geologic structure,evoked process and movement mode.The structure of low inclined sliding-resistance region of the bedding body link is a typical structure fraught with high-speed landslide.The body movement mode of the landslide is a high-speed monoblock sliding which lead the fluidization of the clay in the shear zone.The movement is so different from most high-speed landslide.The breaking condition of the landslide rock mass is of significant reference to the research on the starting point of a high-speed clastic flow. |
