摘要：随着水库的运行，将形成大量的涉水岸坡，库岸滑坡体内地下水浸润线的变化与库水位的波动密切相关。通过不同类型的边坡进行了对比分析，滑体水位与库水位的之间存在着不同的水力联系。通过数值模拟库水位上升与下降时浸润面的解析解与数值解，来了解库水位对滑坡稳定性影响。研究成果表明，库水位上升与下降时滑体稳定性会发生显著变化，其与坡体本身性质和库水变化情况都有着密切的联系。

Abstract：With the operation of the reservoir, the formation of large amount of hydrous slope, reservoir bank landslide in groundwater infiltration line and the change of reservoir water level fluctuation is closely related to. Through different types of slope analysis, there is a difference between the water level and the water level of the sliding body. Through numerical simulation of the analytical solution and numerical solution of the reservoir water level rising and falling, the influence of reservoir water level on landslide stability is understood. The results show that the stability of the sliding body can be changed significantly when the water level rises and falls, which

is closely related to the nature of the slope and the changes of the reservoir water.

Key words：landslide；reservoir water level；groundwater level；numerical simulation ；infiltrated surface
