爽岛水电站滑雪道锥面帖角倒悬扭曲面挑坎的研究应用

Research and application of deflecting bucket with the warped surface conic shaped and hung inversely of ski run of the Shuangdao hydropower station

利用锥面帖角倒悬扭曲面挑坎，控制射流导向，形成三维挑流水舌，水舌沿程扩散、碰撞、掺气良好，并在下游水垫中产生了三元水跃，较大幅度地提高了下泄水流的综合消能率，达到良好的消能防冲效果。将该挑坎应用于爽岛水电站滑雪道改造，经过现场泄洪测试和近５年的工程运行检验，证明了试验效果和应用情况良好。

Using the deflecting bucket with wraped surface , conic shaped and inversely hung , we enable controlling jet flow direction guide , forming tridimensional deflecting nappe , spreading along the path , ternary jump , ect. . Then a better energy dissipation and erosion prevention effect reaches . It has been applied in the Shuangdao hydropower station for 5 years . Through practical running and testing , it proved the situation good.
