摘　　要：某枢纽船闸所处航道沿线水资源匮乏,且船闸一次输水过程耗水量大,船闸需带省水功能。根据船闸最大工作水头及闸址地形条件,提出采用带1个省水池的短廊道集中输水系统布置方案。为解决省水船闸设计中的输水系统布置的水力学关键技术难题,通过采用130物理模型,对船闸非省水运行和省水运行时的输水系统水力特性、船舶(队)停泊条件进行了试验研究。结果表明:采用的输水系统布置合理可行,各项输水水力指标满足规范和设计要求。Due to the channel that a ship lock located is lack of water resources,and the water consumption of one filling and emptying process is large,the ship lock should have water-saving function.According to the maximum difference between water level and the topographic conditions of the lock site,we propose a short-culvert filling and emptying system with a water-saving pool.To solve the key hydraulic problems of the filling and emptying system layout during the design of water-saving ship lock,we test the hydraulic characteristics and berthing conditions during lock filling and emptying with non-water-saving and water-saving operations by lock physical model with a scale of 1:30.The results show that the layout of the filling and emptying system is reasonable and feasible,and the hydraulic characteristics meet the specifications and design requirements.
