摘要
水库溢洪道控制段一般为溢流堰形式,而堰体中有泄水洞的溢流堰在水利工程中并不多见。通过以黑山口水库溢洪道溢流堰为例,采用三维数值模拟方法,研究了带泄水洞溢流堰泄洪时的当量流量系数、流态等水力特性,为水利工程设计提供参考。
The control section of the spillway in the reservoir generally is the spilling weir. But the spill-weir with the sluice culvert is infrequent in the hydraulic work. Taking the Heishankou reservoir as a case by using the method of the 3-D numerical simulation, this paper studies the vari- able rules of the equivalent flow coefficient and flow pattern about the spill-weir with the sluice culvert,which can be a designing reference for the hydraulic engineering.
