摘　　要：在1∶15引水隧洞水工单体模型上,针对某大型引水工程洞内衔接池在部分高弗氏数水流条件下存在跃后波浪大、长距离明流洞洞顶余幅不够等问题,研究了5种跃后消波方案。结果表明:单层压板式消波方案较难适应运行水头或流量变幅大的工程;垂直平齐均匀排布消波方案阻水较明显,其跃首前移和池内水面升高也相对较大;采用分层布置、各层有适当错距的消波梁方案,明流洞内消波效果较好。在此基础上提出的两级消波梁方案,明流洞内的最大波幅降低约66.7%,满足了长距离明流输水隧洞对洞顶余幅的要求。Based on the monomer hydraulic model of the 1∶15 water diversion tunnel,five post-jump wave dissipation measures were studied to solve the problems of large post-jump waves and insufficient roof margin of long-distance open-flow tunnel in the connection pool of a large water diversion project under the condition of high Froude number flow.The results show that the single-layer pressure plate wave dissipation measure is difficult to adapt to projects with large operating head or flow amplitude;and the water resistance of the vertically flush and evenly arranged wave dissipation measure is obvious,and the head of the jump forward and the water level in the pool are relatively large.The wave dissipation beams measure with layered arrangement and appropriate staggering of each layer is adopted,and the effect in the open-flow tunnel is better.On this basis,the two-stage wave dissipation beams measure proposed reduces the maximum amplitude in the open-flow tunnel by about 66.7%,which meets the requirements of the long-distance open-flow water conveyance tunnel for the roof margin.
