| Abstract: | Based on 3-D nonlinear dynamic FEM, taking a high core rockfill dam as study object, earthquake-induced permanent deformation and dynamic stability evaluation methods are proposed. Using the proposed methods, seismic response of the high core rockfill dam, especially the earthquake-induced permanent deformation, the dam body element anti-seismic safety, dynamic stability of dam slope are studied. The results and conclusions are valuable for engineering construction. |
