摘　　要：长江取水工程结构设计是长江沿线城市给水设施建设的重要内容之一,决定了取水工程的造价,结构方案的合理性在一定程度上决定了以长江为水源的给水工程的成败。本文依托安徽省某长江取水工程,介绍了取水头部、自流管、取水泵房等结构方案和设计要点,浅要分析取水泵房与江堤关系、自流管穿越江堤、沉井施工影响、大流速大冲刷的结构措施等取水工程结构方案的主要关键技术方案及对策,为其他类似江河取水工程结构设计提供借鉴。The structural design of the water-intaking project is the important content of the construction of water supply facilities in cities along the Changjiang river.The rationality of the project determines the project cost,and to some extent determines the success of the water supply project.Based on the Changjiang River water project in A nhui province,this paper introduced the structure scheme and design points of the intake head,artesian pipe and intake pumping house.The key technical schemes and countermeasures of water intake engineering structure scheme were analyzed in this paper,such as the relationship between the intake pump house and the riverbank,the artesian pipe crossing the riverbank,the influence of caisson construction and the structural measures for the large flow rate and serious erosion.This paper should provide reference to the structure design of other similar river water-intaking projects.
