摘　　要：河床式水电站的机组运行方式决定着尾水渠的流态,将显著影响尾水渠泄流的集鱼、诱鱼效果。建立数学模型对银江水电站尾水渠泄流开展了数值模拟,结合过鱼对象的游泳能力和生活习性,分析了尾水渠泄流与洄游鱼类上溯的适宜度。结果表明:银江水电站尾水渠的泄流适合鱼类上溯,且选择靠近进鱼口的机组泄流更有利于吸引鱼类在进鱼口聚集。The operation mode of the riverbed hydropower project units determines the flow state of the tailwater channel,which will significantly affect the fish collection and lure effect of the tailwater channel discharge.A mathematical model was established to numerically simulate the discharge of the tailwater channel of Yinjiang Hydropower Project.Based on the swimming ability and living habits of fish passing through,the suitability of tailwater channel discharge and upstream migration of migratory fish was analyzed.The results indicate that the discharge of the tailwater channel of Yinjiang Hydropower Project is suitable for upstream fish,and selecting units near the fish inlet for discharge is more conducive to attracting fish to gather at the inlet.
