水库溢洪道受其地形、地质条件限制,在陡槽段不得不设置弯道.针对云南省某水库溢洪道,通过水工模型试验研究,水流通过陡槽弯道后产生了不对称冲击波,水流分布极不均匀,水流流态紊乱,下游消能能力严重不足.为解决这些问题,经反复试验,最终在陡槽弯道段底部垂直布置了四道斜槛.采用这种工程措施,起到了消减急流冲击波,改善陡槽弯道水流流态,提高下游消能能力的良好效果,可为同类工程提供一定参考.

For the spillway of a reservoir in Yunnan Province,by hydraulic model test,we have known the water flow brings into the asymmetric shock wave when it passes the curved channel of chute,the distribution of water flow is uneven,the flow pattern is disorder and the ability of energy dissipation is seriously inadequate.After some tests,four sloping sills at the bottom of curved channel of chute are set up finally.Using that engineering measure can have great effects on eliminating the sault shock wave,improving the flow pattern of curved channel and increasing the ability of energy dissipation.
