摘要
三大峡水电站水工整体模型试验 ,通过试验研究 ,推荐采用差动坎方案 ,在溢流堰挑坎下游形成交汇水流 ,产生冲击水冠 ,使水舌纵向拉开 ,横向扩散 。
In San Dan Xia Whole hydraulic model practice,By means of model test,Recommend the scheme of dentated sill,In the lower reaches of bucket take shape intersect flow, Produce lash water tongue,Pull apart in the vertical and diffuse in the horizontal,The effect of dissipate energy is notable.
