白杨河水库溢洪道急流收缩段优化模型试验研究OACSTPCD
Experimental study on optimization model for a reservoir spillway rapids contraction
白杨河水库溢洪道模型试验,结果表明原设计方案溢流堰泄流能力不满足设计要求,在急流收缩段形成了严重的冲击波,水流折冲形成水翅超出边墙,收缩段边墙高度不满足安全泄流要求.通过系列试验对设计方案进行修改优化,提出了增加WES堰泄流净宽度和收缩段长度,同时在收缩段设置一小于溢洪道底板坡度的正坡对称多边形孔板消除急流收缩段冲击波的优化方案.优化方案的试验结果表明,溢洪道泄流能力满足泄流要求,急流收缩段内泄洪流态明显改善,折冲水流产生的水翅消除,收缩段水深低…查看全部>>
Through the model test of the Baiyang river reservoir spillway,it shows that the discharge of WES weir under original design scheme condition could not meet the requirements.The strong shock wave is formed in the contraction section,and the water wing formed by deflected stream makes the sidewall height far from meeting the safe discharge.The optimized scheme of increasing WES weir width and contraction section length was put forward by a series of modified …查看全部>>
