摘　　要：通过优化阀门和门楣体型、设置门楣通气管、合理设计门槽尺寸、阀门间歇开启的灌、泄水方式，以控制最大流量；采用顶部突扩的廊道体型，在输水系统构筑物设计中采取水流得到充分消能的措施，解决了高水头船闸槛下分散输水系统应用中的空化、消能等水力学问题。his paper introduces the first application of sill dispersive water conveyance sys-tem(SDWCS)in high-lift navigation lock,in which the hydraulic problems such as cavitation,energy dissipation,etc.have been overcome. In the design of Shaoping Navigation Lock,valves and gate lintel type are optimized,air pipe are equipped to the gate lintel,and the dimension of gate slot is rationally designed.Filling and emptying are operated by intermittent valve opening to control the maximum dis-charge.Gallery is designed with sudden top enlargement of its section,and neces-sary measures are taken in the structure design of SDWCS to ensure complete ener-gy dissipation.
