Abstract
Based on a very high for the project of the concrete face rockfill dam, by three-dimensional finite element analysis method, from the seismic permanent deformation, stress, deformation and stability of dam slope angle of joint panel, this paper demonstrates the ultimate seismic capacity of concrete gravity dam - superhigh face rockfill dam compound structure, the research results show that the dam seismic permanent deformation limit aseismic capacity from 0.65 g to 0.72 g, panel stress seismic limit of 0.7 g, joint dislocation of aseismic capacity limit is 0.8 g, dam slope stability of aseismic capacity limit is 0.43 g. The seismic ability of concrete gravity dam - superhigh face rockfill dam compound structure is strong and can meet the local fortification intensity requirements.
