| 摘 要： | 用有限元方法对双曲拱坝及下游坝面压力管道组合结构进行分析。研究了组合结构的动力相互作用规律和地震频谱输入下的动力响应。结果表明，下游坝面压力管道对拱坝动力特性影响较小，组合结构具有良好的抗震性能。

| Abstract: | The seismic behavior of the arch dam and down-stream penstocks structure is studied by means of finite element method. The results obtained from response spectrum method show that the down-stream penstocks generaly produce a little impact of the dynamic behavior of .the arch dam and only make the displacements and the stresses of the part of the arch dam change,and that the arch dam and down-stream penstocks structure has a good anti-seismic hehavior. |
