Abstract:

The groundwater in slope is one of the main factors that affect its stability. Draining water from slope can prevent the landslide from booting. The feasibility of applying compressed air to drain water in slope engineering by using basic theory model test was analyzed. It is concluded that this drainage method for slope is feasible and applicable to soil with pores radius above 5.0 μm，and the process of draining water with pressure air has the initial pressure. The drainage rate presents a proportional relation to the permeability coefficient and air pressure, and an inverse relation to the water head and pore radius. The preferential flow could be observed in bigger pores.

Key words: slope, saturated soil, discharge water with compressed air, initial air pressure, preferential flow
