摘要:
为研究涉水滑坡受库水位升降及降雨作用变形机制及稳定性影响，以白家包滑坡为例，采用数值模拟方法，分析其在145 m、162 m和175 m水位、20年和50年降雨强度、1.2 m/d和2.0 m/d渗透系数等不同工况组合条件下的渗流分布和稳定性系数。结果表明：随库水位上升，白家包滑坡整体趋于稳定状态，且稳定性系数会出现增长趋势；库水位下降，白家包滑坡稳定性系数呈现下降趋势。考虑降雨组合作用，水位下降速率越大，滑坡变形程度越大。
Abstract:
In order to study the deformation mechanism and stability of Wade landslide affected by the rise and fall of reservoir water level and rainfall, the seepage distribution and stability coefficient of Baijiabao Landslide under different combination conditions such as 145m, 162m and 175m water level, rainfall intensity in 20 and 50 years, permeability coefficient of 1.2m/d and 2.0m/d were analyzed by numerical simulation. The results show that with the rise of reservoir water level, Baijiabao Landslide tends to be stable as a whole, and the stability coefficient tends to increase; with the decline of reservoir water level, the stability coefficient of Baijiabao Landslide tends to decrease. Considering the combined effect of rainfall, the greater the rate of water level decline, the greater the degree of landslide deformation.
