| Abstract: | Based on 3-D nonlinear dynamic FEM method,taking a high concrete faced rockfill dam(CFRD) as study object,a set of comprehensive seismic safety evaluation method for the dam is proposed.The acceleration response and shear stress response,the stress and joint displacement of the concrete face,the earthquake-induced permanent deformation,the element anti-seismic safety,the dynamic stability of dam slope are studied.The proposed evaluation method and conclusions are valuable for engineering construction. |
