摘　　要：龙船厂航电枢纽工程坝址区域河道狭窄、弯曲,设计初拟方案的船闸下游引航道导航墙布置占据了河道部分过水断面,严重影响泄洪闸的泄流能力,且其下游引航道口门区流态和流速无法满足通航的要求。通过水力模型试验,优化了船闸上、下游引航道导航墙的布置和长度,明显增大了泄洪闸的泄流能力,改善了船闸上、下游引航道口门区的运行流态,满足了船闸通航的要求。The dam site of Longchuanchang navigation power junction is located in a narrow and curved river.In the initial design plan, the channel part of the cross section was occupied by the guide wall of the lock downstream approach channel, so the discharge capacity of the sluice was effected seriously.And the flow pattern and velocity of the downstream outlet area of approach channel cannot meet the navigation requirements.Based on the hydraulic model test, the layout and length of the guide walls of the upstream and downstream approach channel are optimized, and hence the discharge capacity of the sluice was increased significantly, the flow pattern of the outlet area are improved dramatically , and the navigation requirement of the lock are satisfied.
