摘　　要：老挝萨拉康水电站船闸是湄公河航运干线中重要的通航工程,其船闸规模为120 m×12 m×4 m(有效长度×宽度×门槛水深),设计水头为20 m。根据萨拉康船闸的整体布置及《船闸输水系统设计规范》的相关规定,研究论证了船闸可采用的2种输水系统形式——闸底长廊道侧支孔输水系统及闸墙长廊道闸底横支廊道输水系统。通过体形比较、计算分析以及水工模型试验研究,比较2种输水系统的优缺点,选取合理方案,保证船闸安全高效运行。The ship lock of Sanakham hydropower project in Laos is the critical navigation works in the Mekong River shipping route.The lock scale is 120 m×12 m×4 m（effective length×width×sill water depth）.The design head is 20m.According to the general layout of the ship lock and the regulations of Design Specification of Ship Lock Water System,it is justified that 2 water system types can be adopted for the lock-the hole water transfer system along the long gallery at the lock bottom and the latitudinal gallery water transfer system at the lock bottom of the lock wall long galley.Based on outline comparison,calculation and hydraulic model test,this paper compares the advantages and disadvantages of the 2 water systems,so as to select the reasonable solution and ensure the safe and efficient operation of the ship lock.
