【Abstract】 Dynamic response analysis of a CFRD with extrusion-sidewall structure is performed by using the finite element method(FEM).The extrusion-sidewall structure is simulated by an equivalent numerical model.The dam filling materials are supposed to be an equivalent linear viscoelastic model developed by Shenzhujiang.The dynamic response of the dam in high seismic region is evaluated including the dynamic deformation and residual deformation of the dam,stress and deformation distribution of its face slab and the deformation of the peripheral joint.更多还原
