| 摘 要： | 首先介绍了钢筋混凝土渡槽结构在地震荷载作用下的分析理论,根据这些理论建立了渡槽结构的动力有限元分析模型,分别采用干模态法、附加质量法和ALE法考虑渡槽结构液固耦合作用,通过具体的工程算例,对钢筋混凝土渡槽结构进行了不同工况下的数值模拟研究,包括混凝土非线性材料分析、渡槽结构静水与动水响应分析、渡槽结构自振特性分析和槽墩的能力曲线分析。研究表明,考虑固液耦合作用的渡槽实体有限元模型能较好地模拟渡槽结构地震反应,并得到相应的渡槽结构地震反应规律。

| Abstract: | In this paper,the method for calculating the seismic response of reinforced concrete aqueduct is introduced.The dynamic finite element model of the aqueduct is built.The numerical simulation is conducted to reproduce the whole process of the work of aqueduct under different conditions,and the result is used to design the real project.The analysis includes the nonlinear behavior of the reinforced concrete material,the static and dynamic interaction between the fluid and the structure and the capability curves of the piers of the aqueduct system.Finally,some laws of the seismic response of the aqueduct system are summarized. |
