【摘要】 韩江高陂水利枢纽电站上游进水渠布置涉及其运行流态、泄水闸泄流能力、鱼道运行等因素。通过水力模型试验,取消了设计初拟方案的电站进水渠左侧实体导墙布置,将进水渠左导墙和拦沙坎修改为多孔拦污栅闸孔布置形式,调整了拦沙坎顶拦污栅闸孔轴线与闸坝轴线的交角,并减小进水渠进水斜坡段的坡度等。这些措施明显改善了进水渠的入流条件和运行流态,满足了泄水闸泄流能力和鱼道运行的要求,降低了进水渠内流速,减小进水渠段的水头损失。研究成果得到了工程设计的采用,可供类似工程设计参考。更多还原

【Abstract】 The layout of the upstream water inlet channel of Gaobei Hydropower Station at Hanjiang involves the operation flow pattern,sluice discharge capacity,and fishway operation etc.. Through the hydraulic model test,the measures are adopted,such as cancelling the initial design scheme of the left solid guide wall layout of the channel,the left guide wall and debris barrier have been modified as layout of the multiple trash rack gated pore,adjusting the angle between the trash rack gated pore axis laying on the debris barrier top and the sluice axis,and decreasing the slope of the water inlet slope section,etc.. Through these measures,the inflow condition and operation flow pattern of the channel are significantly improved,the sluice discharge capacity and the fishway operation requirements are satisfied,the flow velocity and the head loss of the channel section are reduced. The research results have been adopted in engineering design,and can be used for a reference for similar engineering design.更多还原
