摘　　要：蜀山泵站枢纽船闸对引江济淮工程航运至关重要,是连通长江与淮河,确保引江济淮航运干线畅通的控制性工程,其闸室规模大、工作水头高、输水能量高,输水过程水力学问题是船闸设计的关键环节。结合工程地质和结构设计,船闸拟采用形式最为简单的闸墙长廊道侧支孔输水系统,输水过程船舶与船闸自身安全能否满足相关要求需要开展细致研究。通过比尺为1∶25的物理模型试验,对其输水过程船舶停泊条件、水力特性及引航道水流条件开展研究。结果表明:在推荐的输水系统布置和阀门开启方式下,各项水力指标均能满足规范和设计要求。The lock of Shushan Pump Station plays an important role in navigation of Yangtze-to-Huai waterdiversion project,which is one of the controlling projects to keep smooth navigation from the Yangtze River to theHuai River.The lock has typical characteristics such as large chamber,high lift and huge flow energy,so thehydraulic problem becomes a key part in lock design.Considering the geology and structure design,the lock tends tobe used the simplest dispersed filling and emptying system,the wall-culvert side-port type.It needs to be detailedstudied that if the safety of vessels and lock itself during filling and emptying can satisfy the design demands.Theship berthing condition in lock chamber,the hydrodynamic characteristics and flow conditions in approach channelsare all studied by a1:25scaled physical model.The results indicate that,all the key parameters can satisfy the needsof codes and design under the recommended lock layout and valve opening patterns.
