Abstract:

The method of intercepting water with compressed air for a landslide is mainly based on the unsaturated seepage theory, through filling the trailing edge of slope with compressed air to expel some groundwater, to form the unsaturated curtain belt, to intercept the groundwater seepage from the trailing edge of slope, and then to lower the groundwater level in a potential landslide. The multiphase seepage is quite complex, so the simulation technology is often the effective research method. Based on the groundwater level and the seepage quantity in the landslide model test, it's easy to get the soil parameter through numerical inversion analysis. To study the effects of groundwater level in potential landslide caused by different inflatable positions through constructing the numerical model, the authors get the conclusions as follows:the groundwater level of potential landslide area can be lowered by filling and inflating the trailing edge of slope with compressed air; a better inflatable position should be closed to the potential landslide area. The greater the pressure of the inflatable point is, the more the groundwater level of the potential landslide area drops. When choosing the depth of the inflatable point, we should select a deeper one, so that a larger air pressure can be used.

Key words: landslide, groundwater, the method of intercepting groundwater with compressed air, model test, numerical simulation
