| 摘 要： | 采用有限元软件对某水利枢纽非溢流坝段进行抗震分析,建立非溢流坝段的动力计算模型,进行模态求解、反应谱分析。通过动力有限元的计算分析,表明在坝踵回填混凝土之后,坝体的应力状态得到了显著改善。

| Abstract: | The earthquake resistant analysis of non-overflow dam in a water complex is made with finite element software. The dynamic calculation model of non-overflow dam is established for model calculation and response spectrum analysis. The result of dynamic finite element calculation indicates that the stress state of dam is improved evidently after backfilling concrete. |
