Based on the 3 D FEM,the deformation of the Shuibuya concrete faced rock fill dam is calculated by use of a rheological model.The differences between the deformation of the structure obtained in consideration of rheology of rockfill and that from conventional models are as follows: the slope compression stress of the slab increases and the slope extension stress decreases;however, the axial compression stress increases in the middle area,and the axial extension stress also increases near the abutment a...
