摘　　要：针对龙潭水电站引航道区域不利水流影响船舶进出安全问题,为改善上、下游引航道及口门区的流速,进行了优化上、下游引航道导航墙延长方案的研究。建立龙潭水电站船闸整改物理模型,研究运行过程中的各个典型工况。得出结论:1)上游河道来流量大于1100 m^(3) s、闸门全开泄洪时,上游引航道口门区水流条件仍不能满足规范要求。2)下游引航道将主导航墙由透水改为不透水后,引航道及口门区水流条件可满足规范要求的结果。The unfavorable water flow in the approach channel area of the Longtan hydropower station affects the access safety of ships.To improve the flow velocity of the upstream and downstream approach channels and the entrance area,this study optimizes the extension scheme of the navigation wall of the upstream and downstream approach channels.Specifically,we build a physical ship-lock rectification model of the Longtan hydropower station to study each typical working condition in the operation process.The following conclusions are drawn:1)When the flow rate of the upstream river channel is greater than 1100 m^(3) s,and the ship lock is fully opened,the water flow conditions in the entrance area of the upstream approach channel still cannot meet the requirements of the specification.2)After the downstream approach channel changes the main navigation wall from permeable to impermeable,the flow conditions of the approach channel and the entrance area can meet the requirements of the specification.
