Abstract: Based on the pre-study of the related research，the failure mechanisMfor Fariy·River shore slope which is located in Fairy-River scenic area of sorcery mountain is analyzed，because of the water level’S change between the Three Gorges Reservoir retains water front and back．It is key part to prevent and cure a database shore slippery ascent by analyzing the formation mechanisM’S break．All the same，simple statement the calculation method about the slop’S stability analysis un- der the water level change situation ． What’S more，it is required to discuss the shore slope cause of second-class slope， and some prevention and cure counterplots are put forward．

Key words: water level change, shore ascent stability, mechanisMof breakdown, stability analysis

摘要： 在相关文献研究的基础上，列举出诱发巫山神女溪滑坡的因素，从而分析巫山神女溪由于三峡水库蓄水前后， 水位变动诱发库岸滑坡的机理，研究其破坏形成机制是防治库岸滑坡的核心。简述在库水位变化情况下，岸坡库水 间相互作用及其岸坡稳定性分析的计算方法
