摘要
拉西瓦水电站底孔弧形闸门设计水头较高,运行工况有电站初期发电及渡汛水位的局开运行和电站建成后的全开运行等多种工况,设计难度较大。文章对拉西瓦水电站底孔弧形闸门的闸门与止水选型设计、结构布置、闸门水力学研究与闸室体形设计、结构设计中的动力稳定问题、荷载分析、启闭机位置与容量的选定、锁定设计及偏心铰弧门偏心参数确定等作了较为详细的介绍。
In view of high design head for the eccentric hinge radial gate of Laxiwa hydropower project and various operation cases such as partial open operation at initial power generation flood control water level and full open operation after completion of the project,the design of the eccentric hinge gate for the bottom outlet is quite difficult.This paper presents in detail the type selection design of bottom outlet radial gate and water stops,structure layout,gate hydraulics study gate chamber outline design,as well as dynamic stability in structure design,load analysis,selection of gate hoist location and capacity,locking design,and the determination of eccentricity parameters for the eccentric hinge radial gate.
