Abstract：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.

Key words： slope engineering landslide underground water displacing water with compressed air unsaturated soil numerical simulation physical model
