摘　　要：山溪性河流上梯级枢纽开发,由于河道水浅、滩多、弯道多,给枢纽整体布置带来较大困难,以天马枢纽为依托,建立了比尺为1∶100的枢纽整体水力学物理模型,采用超声波多普勒测速技术(ADV)研究了船闸口门区的水流条件。试验结果表明,原枢纽布置方案下,上游停泊段未做掩护措施,船闸口门区流速过大,不利于通航;调整航道中心线后,修建隔流墙及调整泄洪闸的运行方式均可改善上游船闸的通航水流条件,在考虑河道的行洪后,推荐使用调整泄洪闸运行方式的措施。为天马枢纽单线船闸工程通航水流条件改善提供技术支持,同时亦为其他山溪性河流上的船闸改善通航水流条件提供了参考。Due to the shallow water,many beaches and many bends in the river,the overall arrangement of the hub poses great difficulties.In this paper,based on the Tianma hub,the overall hydraulics physical model of the hub with a scale of 1:100 is established,and the water flow conditions in the gate area of the locks are studied by using ACOUSTIC Doppler Velocimeter(ADV).The test results show that under the original hub layout plan,the upstream mooring section is not covered,and the flow velocity in the gate area of the locks is too large,which is not conducive to navigation;After adjusting the centerline of the channel,constructing the flow divider wall and adjusting the operation mode of the floodgate can improve the navigable flow conditions of the upstream locks.After considering the flooding of the river,the measure of adjusting the operation mode of the floodgate is recommended.This test can provide technical support for the improvement of navigable water flow conditions of the single-line ship lock project at Tianma Junction,and provide reference for the improvement of navigable water flow conditions of ship locks on other mountain streams.
