摘　　要：通过整体定床物理模型试验和船模通航试验,对剑潭水利枢纽船闸下引航道通航水流条件进行研究。结果表明:原设计方案口门区回流流速和连接段横向流速超标,不满足安全通航要求。采用缩短隔流墙的措施对方案进行了优化,并提出推荐方案,改善口门区及连接段的通航水流条件,同时满足防洪要求。Through the overall fixed bed physical model tests and the ship model navigation tests,the navigable flow condition of the lower approach channel of the ship lock of the Jiantan hydro-junction was studied.The results showed that in the original design,the flow velocity of the entrance area and the lateral flow velocity of the connecting section exceed the standard,which did not meet the requirements for safe navigation.The scheme was optimized by shortening the partition wall.Finally,the recommended scheme has improved the navigation flow conditions of the entrance area and the connecting section and met the flood control requirements.
