| 摘 要： | 地震激励下处于深水中的桥墩和周围水体的相互作用将对桥梁结构的动力响应产生较大影响。首先对地震作用下水-桥墩的相互作用理论做了概括,给出了动水压力对桥墩的作用效应及各自的适用范围;对主要的三种考虑流固耦合效应的分析方法做了对比,探讨了地震作用下影响水-结构相互作用的主要因素,并对今后的研究提出了建议。

| Abstract: | Under earthquake excitation,the interaction between the bridge piers in deep water and the surrounding water bodies will affect the dynamic response of the bridge structure. The paper outlines the theories on the interaction of water-pier under earthquake excitation,and lists the application scope of the action effects of the hydrodynamic pressure to the bridge pier. Meanwhile,the paper compares the three main analysis methods considering fluid-structure interaction effects,and discusses the main factors of water-structure interaction under earthquake excitation. Suggestions for the future researches are proposed finally. |
