摘　　要：鉴于过鱼设施进口区域集诱鱼效果是影响过鱼效率的关键因素之,提出了一种新的旁道跌流诱鱼优化思路,将上游水流以跌流形式补水至鱼道进口外区域,通过挑流板等辅助设施使平面流场内形成水平吸引流,并依托大渡河沙坪一级水电站鱼道工程,建立了大比尺物理模型进行方案论证及优化,分析了过鱼设施进口附近流场特性,探讨了诱鱼的可能性。试验结果表明,采用一次跌落方案更有利于平面流场内对洄游鱼类形成吸引流,流速为0.3-0.5 m/s,且进口区域流态信息丰富,适宜鱼类聚集。The effect of luring fish is one of the key factors affecting fish passing efficiency in the entrance area of fish-passing facilities.Proposed a new optimization idea of side-channel drop-flow to lure fish.The upstream water was re-plenished to the area outside the fishway entrance as drop-flow.With the help of auxiliary facilities such as cantilever plate,the attractive flow was formed in the horizontal orientation.Take the fishway project of Shaping I Hydropower Station as example,a large scale physical model was established to demonstrate and optimize the scheme,and the flow pattern near the entrance of the fish-passing facility were analyzed,and the possibility of attracting fish was discussed.The experimental results show that the one-dop scheme is favorable for attracting the migratory fish in the horizontal ori-entation,with the flow velocity of 0.3-0.5 m/s,and the information of flow pattern is rich in the entrance area,which is suitable for fish aggregation.
