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。
The finite element method is used to analyze the composite structure of the double curvature arch dam and the downstream pressure surface. The dynamic interaction of composite structures and the dynamic response of seismic spectrum input are studied. The results show that the downstream dam pressure pipe has little effect on the dynamic characteristics of the arch dam, and the composite structure has good seismic performance.
