摘要
随着全球水资源的日益缺乏,我国的水资源问题亦日益突出。许多地方缺水严重,有效开展水资源的合理利用已成为缺水地区的首要任务。部分引水工程的弧形闸门需要进行小开度局部开启操作,以调节流量。本文根据某引水工程弧形闸门流激振动原型观测结果,从闸门结构的振动量、振动位移、动应力、结构动力特性等方面评价弧形闸门小开度运行振动特性及其安全性。其研究成果对其他水电工程的表孔弧形闸门的运行操作亦具有一定的指导意义。
With increasing shortage of water resources in the whole earth, our country＇ s water resources question is sticking out day by day. In many places water-shorting becomes a serious question, rational and effective use of water resource becomes an important task. In part diversion works, radial gates are needed to operate partly for adjastment of discharge. Based on prototype observation, this paper studies the flow-induced vibration of the radial gate in some engineering, the gate vibration amplitude, vibration displacement, vibration stress, dynamic character and so on. Operation safety and vibration character of the gate under little opening are evaluated. The study result has certain guiding sense to similar engineering.
