摘　　要：采用正态1:20整体物理模型,对竖缝式鱼道及仿自然通道2种鱼道型式进行水力学试验研究。重点研究了不同流量下,鱼道内沿程水位、比降及流速等水力要素变化。进而优化了鱼道主、辅进鱼口结构形式,以及鱼道平面布置、鱼道长度、底坡、竖缝宽度及池室个数。通过对鱼道总体布置、池室结构、鱼道泄流量、沿程水位及比降变化、沿程水流流速变化,以及鱼道施工与运行维护等多方面综合比选,提出了适宜依兰航电枢纽的鱼道优化方案。The vertical-slot fishway and the natural imitated fishway were studied through hydraulics primary and secondary structure,length, bottom slope,slit width and pool room number of the fishway were optimized.The fishway optimization scheme for Yilan navigation-power junction project was proposed through comprehensive comparison of fishway general layout,pool room structure,discharge volume,water level, gradient ratio changes,flow velocity variation, fishway construction, operation and maintenance.
