摘要
利用水工水力学模型试验研究方法对圆满贯工程泄洪消能问题进行研究分析同时,为百米级拱坝在五表孔布置方面,提供了一种全新的泄洪消能工体型与设计思路,即采用宽尾墩窄缝纵向水舌与连续鼻坎横向扩散的布置形式,可以使水舌在纵向与横向实现全范围的扩散,消能率提高,适应不同运行方式需要的同时,缩短了RCC拱坝施工工期,节约了工程总投资。
The experimental study on energy dissipation for Yuanmanguan Power Station was car-ried out by the hydraulic model test, put forward a new energy dissipator style and its designing method on five crest spillway flood for arch dam. The new energy dissipator is constituted by flaring gate pier and deflector bucket. Spillway flow would be spreaded in cross and longitude. Energy dissipation ratio would be increased, the period of RCC arch dam construction and gross engineering investment would be reduced.
