摘　　要：八堡船闸为中国首座在强涌潮河段双线同时新建的1000 t级船闸,是继三堡船闸后第二个连接京杭大运河和钱塘江的水上交通枢纽。通过对船闸无水、平水及常水位条件下输水系统的观测,掌握阀门启闭特性及闸室输水水力特性,为保障船闸安全、高效运行提供依据。观测表明:船闸阀门运转稳定,阀门油压机启闭力均满足设计要求,短廊道集中输水系统整体消能布置较好,闸室水位变化平稳、进出口水流流态良好,船闸能够安全运行和高效通航。Babao Lock is the first dual-line 1,000-ton-class ship lock newly constructed in a strong tidal river section in China and the second water transportation hub connecting the Beijing-Hangzhou Grand Canal and the Qiantang River,following Sanbao Lock.Prototype observations under conditions of no water,still water,and constant water levels were conducted to investigate the valve operation characteristics and the hydraulic characteristics of the filling system,providing a basis for ensuring safe and efficient lock operation.Observations indicate that the lock valves operate stably,with opening and closing forces meeting design requirements.The energy dissipation layout of the short culvert centralized filling system is effective,chamber water level variations are smooth,and flow patterns at the inlet and outlet are favorable.The lock demonstrates safe operation and efficient navigation performance.
