摘　　要：途述了我国第一座采用槛下闸底廊道二区段出水的分散输水系统船闸———广西昭平电站船闸 (水头 2 0m ,闸室有效尺寸为 6 0m× 8m× 1 5m) 1∶2 0输水系统水工整体模型及 1∶16阀门段减压模型试验成果 ,并对闸室输水水力特性及船舶停泊条件、空腹式输水阀门廊道段的水力特性 ,包括阀门的阻力系数、收缩系数、阀门后水流收缩断面的最低压力以及阀门的空化特性和减免空蚀措施等方面作了介绍。原型运转表明 。The ZHS ship lock,in China,is the first one of water delivery system in dispersion mode of delivering water through gallery No.2 sector under the sill.The authors discussed the test result of 1:20 water delivery hydraulic integral model and 1:16 valve pressure reduction mode,and introduced the rocky water delivery hydraulic characteristics,ship berth condition and hydraulic characteristics of spandrel water delivery valve gallery sector,etc.Prototype operation has proved that the hydraulic condition of the ship lock was satisfied.
