| 摘 要： | 清江水布垭大岩淌滑坡位于水布垭水电站坝址区后部，正处于溢洪道泄洪时产生的雾化强暴雨中心地带，这种强雾化雨会显著影响滑坡体内的地下水分布，并给滑坡体的稳定带来不良后果。利用三维饱和非饱和稳定渗流有限元法对大岩淌滑坡在天然降雨以及高强度雾化降雨条件下的地下水流场分布进行了计算分析，后比较了滑体不同防、排渗措施的渗控效果。

| Abstract: | The Dayantang landslide is located at the dam’s back side of Shuibuya hydrolic project in Qing river, and it is in the center of strong atomized rain brought by flood discharging of spillway. For atomized rain influences groundwater table of landslide obviously, the stability of landslide is not optimistic. This paper simulated groundwater table of the landslide under natural rain and high atomized rain with three-dimensional saturated-unsaturated stable seepage finite element method, and mostly compared the seepage-control effects of different anti-seepage measures. |
