Abstract: Taking Qingquanlu (Yuanjiadeng)landslide , situated in Wanzhou of Chongqing city , as an example of loose Earth landslide and based on stability calculating of six modes fitting to landslides located at bank of the Three Gorges Reservoir in this paper , the author analyzes stability trend in detail for the landlide to develop .All research results identify that the mode of the decrease of reservoir level is key mode to control stability of the landslide andmust be control mode in harness of the landslide

Key words: bank of the Three Gorges Reservoir , loose Earth landslide , stability , mode , the decrease of reservoir level

摘要： 以重庆市万州区清泉路(袁家蹬)滑坡为例，基于对适宜于库岸滑坡稳定特性的6种工况的计算，对三峡 库岸散体滑坡稳定态势进行了分析。研究结果表明，库水位降落是库岸滑坡稳定性变化的控制工况，此工况应该 作为滑坡治理的设计工况
