针对瓦村水电站溢洪道出口水流挑距过大、水舌空间扩散效果不佳、入水区域集中、泄洪消能效果差及泄槽内水翅现象严重等问题,采用比尺为1∶60的正态物理模型对溢洪道体型进行优化试验研究。结果表明,在闸墩尾部加设尾墩,使泄槽段水流流态有了极大的改善,水流平顺,基本上消除了水翅现象;采用连续燕尾挑坎使溢洪道出口水舌合理归槽,空中扩散效果良好,解决了入水集中的问题,消能效果较好,所提挑坎布置形式可供相关工程参考。 In view of the problems such as the overwhelming water flow at the spillway exit of Valun hydropower station, the ineffective diffusion of the water tongue, the concentrated water intake area, the poor flood discharge energy dissipation effect and the serious water fin phenomenon in the drainage trough, Physical Model Optimization Study on Spillway Body Shape. The results show that the tail pier is added at the tail of the sluice pier so as to greatly improve the water flow pattern in the sluice section. The flow is smooth and water fin is basically eliminated. , The effect of air diffusion is good, to solve the problem of water concentration, energy dissipation is better, the type of the proposed Bucket layout for the relevant project reference.
