Analysis on Features and Causes of Wujiawan Landslide in Wanzhou City of the Three Gorges Area

基于吴家湾滑坡的地理位置及地质环境条件 ,从滑坡周界、滑坡体与滑带的物质结构特征、滑床、滑坡变形破坏迹象等 ,深入分析了吴家湾滑坡的特征 ;在此基础上进一步分析了吴家湾滑坡的形成条件及主要控制性因素。本文归纳的吴家湾滑坡形成四个方面的主要条件及两个方面的主控因素 。

Based on the geographical location and geo environment of Wujiawan landslide, the landslide features were analyzed from the aspects of landslide range, the material composition of landslide body and slip strip, landslide bed and the deformation destroyed evidence. Moreover, the formation conditions and main governing factors of Wujiawan landslide were analyzed in depth. Four formation conditions and two governing factors were concluded serving as the basis for stability analysis and the renovation project of Wujiawan landslide.
