摘　　要：研究降雨和库水位升降工况下三峡库岸堆积层滑坡的稳定性。运用二维有限元数值模拟的方法对三峡库岸白龙村滑坡进行瞬态和稳态渗流计算并进行稳定性计算,计算结果表明,白龙村滑坡在库水位上升期间存在一个稳定性较低的水位(159m左右),但之后稳定性升高。在库水位下降期间,稳定性降低。降雨对白龙村滑坡稳定性的影响较大。由此总结出了库岸滑坡稳定性变化的一些初步规律。In this paper,the study on the stability of accumulation landslide in reservoir bank in Three Gorges under the conditions of rainfall and reservoir water level fluctuation has been made.The transient and steady state seepage calculations and stability calculation to the Bailong village landslide in Three Gorges Reservoir bank have been made by using 2-dimensional finite element numerical simulation method.The results show that：there is a lower stable water level（about 159 m） during the water level rising in Bailong village landslide,but the stability increase after that.During the water level drawdown,the stability of landslide is reduced,and with great influence by the rainfall.Thus,we can conclude some preliminary rules on the stability of landslide in reservoir bank.
