大多数滑坡的降雨入渗汇水区在滑坡后缘山坡，后缘的地下水入渗才是导致滑体地下水上升的关键因素。通过气驱水理论分析，并依据土体具有随饱和度降低导水性迅速降低的特性，提出利用充气驱水法在入渗路径上形成含有压气体的非饱和区截水帷幕的构想，并通过数值模拟分析和物理模型试验，得出充气截水减渗效果明显的结论。

Most of landslide′s catchment area is on the trailing edge of slope,and the key factor leading to rise of groundwater level is infiltration of underground water on the trailing edge. The theory of displacing water with air is analyzed. And the hydraulic conductivity will decrease with the decrease in degree of soil saturation. Therefore, the concept is put forward that water stoppage curtain of unsaturated soil area with compressed air is formed on seepage path. The test results prove the validity of intercepting water by using numerical simulation and physical model test.
