Abstract : based on the data obtained from field observations and deformation monitoring, this paper deals with the deformation and failure of a double - decked slope composed of soft rock strata in its lower part and hard - brittle rock strata in its upper part. it is demonstrated that the deformation of this kind of slopes is always initiated by the non - homogeneous rheological compression of the lower soft rock strata, leading to the tension fracture and toppling of the upper hard rock strata, and at last the sliding of the whole deformed body will be caused by the shear failure along the stress - concentration zone in the lower soft rock mass under the actions of the gravitational loading and infiltration water
