在高水头大流量的水利水电工程中,不论泄洪隧洞、高坝底孔或电站进水口都需要高压闸门以控制水流,因而闸门的启闭是关键问题之一。本文系根据我国近年来所进行的模型试验和原型观测资料、同时参考国外有关文献进行综合讨论,以供闸门设计和试验研究人员参考。 In the high water head and large flow of water conservancy and hydropower projects, regardless of flood discharge tunnel, high dam bottom hole or power station inlet require high pressure gate to control water flow, so the gate opening and closing is one of the key issues. In this paper, based on the model tests and prototype observation data carried out by our country in recent years, we also make a comprehensive discussion with references to relevant foreign literature for the reference of gate design and experimental researchers.
