| Abstract: | Evaluation method of earthquake-induced permanent deformation and dynamic stability are proposed based on 3D nonlinear dynamic FEM for the high concrete-faced rockfill dam(CFRD) of Jishixia Hydroelectric Project in meizoseismal area of west China.Using the proposed method,seismic response of the dam,such as the earthquake-induced permanent deformation,element anti-seismic safety,and dynamic stability of concrete face and dam slope are studied. |
