摘要
通过引黄南干7#洞出口明渠梯形薄壁堰的模型试验,对超出规范标准的梯形薄壁堰在自由出流情况下的流量系数利用系列模型递推法进行了确定,与现场超声波流量计对比基本一致。
Through model test of trapezoidal t hin-plate weir in the canal on 7 # tunnel outlet of South Main Line,YRDP,and by means of recursive method of serial models,the discharge coefficient of this weir,in excess of code' s scop e and under free-flowing condition,is determined.By comparision,this result is basically in line with the result surveyed by ultraxonic flowmeter in situ.
