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 control of pumping station control gate with long diversion channel is researched, and numerical calculation is carried out based on the Wanjiazhai Yellow River Diversion Project. The calculation results show that in order to minimize the waste water, the optimal gate adjustment method should offset the unsteady fluctuations caused by the gate action and the pump on and off during the long non-pressure water conveyance tunnel, In the establishment of a constant open channel flow.
