三峡工程库区淹锅沙坝滑坡体特征及稳定性分析

淹锅沙坝滑坡位于长江南岸，跨三峡工程坝51.30km，滑坡体上部为土夹碎块石松散堆积体，下部为基岩滑动形成的块裂体，经对滑坡体进行稳定性分析与计算表明，滑坡体目前状态是基本稳定的，在三峡水库蓄水后，滑坡体前部可能失稳，进而影响滑坡体后部的稳定性。

Characters and Stability Analysis of Yanguoshaba Landslide Group in TGP Reservoir Region

The Yanguoshaba landslide is located at the right bank of the Yangtze River,about 51.3km on the upper stream of the Three Gorges dam site.The slide body consists of two parts, the upper part is the clay which contained crushed stone.The lower part is the large block stone which is shaped through the bedrock sliding.The slide body is stable after careful geological investigation and computation according to the present conditions.But when the Three Gorges reservoir is impounded after the Three Gorges dam is completed,the front part of the landslide body may be failure,further which will affected the stability of the whole landslide body.
