摘　　要：分析了闸涵结构空间薄壁体系的构造特点,研究了箱型结构—水体耦合的求解方程,导出了可用于箱型结构、闸室、渡槽壁面、坝面的动水压力附加质量的统一算式,介绍了地震反应的求解方法。以淮安立交地涵为例,考虑了结构、水体、地基的相互作用,计算了结构的自振特性,分析了7度地震作用时的动力反应,研究方法和研究成果可供闸涵结构的抗震分析和设计参考。The structure characteristic of 3D thinwalled system of lock and culvert is analyzed. The coupling equation of box structure and water body is studied. The unified formula of the additional mass of the dynamic water pressureon the surface of box structure ,lock chamber , flume and dam is derived. The solution method of earthquake response is introduced. Regarding Huaian overhead crossing underground culture as the instance., the interaction of structure, water and its foundation is considered. The free vibration characteristic of the structure is calculated and its dynamic response is analyzed for 7 intensity of earthquake. The suggested method and results can provide reference for seismic analysis and design of lock and culvert structure.
