Abstract: The deformation of a slope and landslide is a very complex problem, and is an importance index value of forecasting and prewarning the landslide hazard. The displacement of slope due to rainfall is related to suction and the stress-strain behavior of unsaturated material. According to test data, the effect of suction on the stress-strain behavior of unsaturated soils is researched; and the moisture content-strain behavior of unsaturated soils is built. Based on this, the mechanism and regularity of slope the displacements due to rainfall have been discussed. The Wudu landslide is analyzed by this theory.

Key words: unsaturated soils, suction, soil-water characteristic curve, constitutive model of unsaturated soils
