Three-dimensional finite element mesh of 150m height Dongqing CFRD is built with advanced grid discretion technology. Under artificial fitting seismic waves with maximum horizontal peak acceleration 0.158g earthquake action, dynamic response of Dongqing CFRD is obtained. Adopting SHEN Zhujiang residual strain model and equivalent viscous-elastic model, the permanent deformation of the Dongqing CFRD is get. The calculation results show that the acceleration and displacement of dam body, dynamic stress of face and displacement of joints are within safety limits and the seismic performance of CFRD could be well guaranteed.
