STUDY ON THE INFLUENCE OF VARIATION OF WATER CONTENT ON SHEAR STRENGTH OF SLIP ZONE SOIL BY TRIAXIAL TEST

The water is one of the dominant factors to landslide stability, and the shear strength choosing of slip zone soil is the key job to landslide stability evaluating and its prevention project designing, so it is very important to develop the influence of variation of water content on shear strength of slip zone soil. The slip zone soil comes from the huge landslide near a hydroelectric station of the upriver section of Yalong river, and the variation of shear strength of its remolding sample has been studied through triaxial test, and the valued variation law of shear strength has got.
