Abstract

Water level fluctuation will soften the rock and soil on the bank, induce the underground water fluctuated and decrease the shear strength, which will have the possibility to cause the stable slope to occur landslide. In this paper, the effort of variations of reservoir water level on landslide stability was disclosed, the buoyancy forces caused by slope partly submerged, the seepage pressure caused by water level rapid drawdown, erosion and devolution in base of the slope combined together affect the stability. The landslide seepage field under different water level conditions was stimulated through FLAC3D. Stability analysis indicates that the water level rise, the safety factor first decreases and then increases; the water level falls, the safety factor decreased gradually.
