摘　　要：针对山区已建高坝枢纽新建通航建筑物轴线布置受河道窄、水头高、电站泄流及已有建筑物影响等条件限制的问题,依托贵州清水江白市水电站枢纽新建通航建筑物工程,采用1∶100正态整体水工模型与自航遥控船模相结合的技术手段,对多条轴线布置方案进行通航水流条件及船舶航行操控研究与优化。试验结果表明,右岸轴线布置方案通航水流条件及船舶航行状态均较好,为推荐方案。研究成果解决了工程关键问题,可供类似已建高坝水利枢纽新建或扩建通航建筑物工程参考借鉴。The axis layout of the newly-built navigation buildings of the built high dam junction in mountainous area is limited by conditions such as the narrow river channel,high water heads,the discharge of power station,and existing buildings.In view of the problems,based on the new navigation building project of Baishi hydropower station in Qingshui River,Guizhou Province,using the technical means of 1100 normal integral hydraulic model and self navigation remote control ship model,the navigation water flow conditions and ship navigation research and optimization of the multiple axis layout schemes are carried out.The test results show that the navigable flow condition and ship navigation state of the right bank axis layout scheme are good,which is the recommended scheme.The research results have solved the key problems of the project,which can be used for reference for the new or expanded navigation building projects of similar high dam water conservancy projects.
