摘　　要：南四湖湖西地区已形成“梯级控制、多级蓄水”的河网体系,在作为东西分界的大沙河上建有大沙河闸、李庄闸等5个梯级控制工程,分别为形成“五级控制、六级水面”调蓄格局。根据现场条件,李庄闸拆建工程设计采用橡胶坝和开敞式水闸两种方案,从技术、经济角度经过方案比选最终采用开敞式水闸方案。结合施工、运行管理等,在设计细节上,采用定型止水接头,增做闸门底坎,消力池采用WES曲线等,既能确保设计质量又能节省投资方便管理。The river network system of“cascade control and multi-level water storage”has been formed in the west area of the Nansihu Lake.The Dasha River,as the boundary between the east and the west,has five cascade control engineering,such as Dasha River Gate and Lizhuang Gate,respectively to form a“five level control and six level water surface”regulation and storage pattern.According to the on-site conditions,two schemes of rubber dam and open sluice gate are adopted in the engineering design of the demolition and construction project of Lizhuang Gate,and the scheme of open sluice gate is finally adopted from the technical and economic point of view.In combination with the construction and operation management,in the design details,the use of shaped fixed water stop joint,the addition of gate sill,and the use of WES curve in the stilling pool can not only ensure the design quality but also save investment and facilitate management.
