| Abstract: | Through seismic response analysis of a concrete-faced rockfill dam in existence by means of 3D finte element method, an anisotropic thin element is advanced to simulate the interface contact between faceplate and rock of concrete-faced rockfill dam and, then, several factors in fluencing on the computation results are discussed. The computation results show that the method presented is simple and convenient to use and meets, moreover, the engineering requirements. |
