摘要
采用三维非线性动力有限元分析方法,针对西部强震区的积石峡水电站工程的高混凝土面板堆石坝,在地震反应分析基础上,应用所建立的分析方法,重点研究了该坝的地震残余变形、坝体单元抗震安全性、面板及坝坡的抗震稳定性,得出了大坝地震残余变形和动力稳定的有关规律和结论,可供工程建设参考。
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.
