EXPERIMENTAL STUDY ON WATER DISTRIBUTION IN LANDSLIDE WITH RESERVOIR TABLE CHANGED

The experimental equipment is established forsimulating water distribution in landslide with reservoir table changed. Thelaboratory model is made based on the shape, geometric characters andsoil-rock ratio of Maoping slide. The water distributions in the simulatedslide are simulated with water table at the half height of the soaredinterface and the height of the first platform. When the reservoir tabledrops down in the experiment, a part of the slide fails. The results showthat wetting lagging is the main factor of slide failure during thereservoir table drop-down.
