带长引水明渠的泵站控制闸门最优调节计算

Study of the Optimal Program for the Sluice Gate of the Pumping Station with Long Inlet Open Channel

本文对带长引水明渠的泵站控制闸门最优调节问题进行了研究，并结合万家寨引黄工程问题进行了数值计算。计算结果表明，为尽可能减少弃水，所采用的闸门优化调节方式应使长无压输水隧洞中因闸门动作与水泵开、停机而产生的非恒定波动相互抵消，以尽快在无压隧洞中建立起明渠恒定流动。

In this paper the optimal regulation problem for the sluice gate of the pumping station with long inlet open channel was studied, and numerical calculation was also made for the regulation program of the sluice gate at Shentongzui Reservoir of Wanjiazhai Yellow River Diversion Project. It seems that to reduce the waste water the optimal program of the sluice gate should be choosen by the following way, i.e., letting the unsteady waves produced by the moving sluice gate and the pumps counteract with each other, then the steady open channel flow could be generated in the long inlet open channel as soon as possible.
