摘　　要：随着近年来极端性天气频繁发生,我国多地沿江城市在汛期内往往会出现超大洪水。对位于江滩上的取水构筑物来说,当超大洪水来临时,如何考虑其对结构的影响,是结构工程师需要面临的问题。文章通过具体的工程实例,阐述了取水头部、原水自流管、取水泵房等主要江滩取水构筑物在超大洪水工况下的受力特性和设计思路,提出了有针对性的计算原则,有较强的可操作性。As extreme weather happens frequently in recent years,massive flood often occurs during the flood season in many alongriver cities.It is a problem for structural engineers to consider the impact of water intake structures on the river bank when the massive flood occurs.Based on a project,the mechanical characteristics and design ideas of water intake structures on the river bank were expounded,such as water intake head,raw water pipe,water intake pump house suffering the massive flood,and the specific calculation principles,which have strong operability,were put forward.
