摘　　要：仿自然型鱼道能有效减轻水利工程建设对鱼类的影响,而鱼道进出口附近的水流条件如何,直接关系到仿自然型鱼道能否应用成功。在分析和总结国内外仿自然型鱼道建设及研究现状的基础上,结合某工程仿自然型鱼道水力学整体模型试验,重点研究了电站不同运行方式下的鱼道进、出口流态,流速分布等水力参数,并进行了活鱼试验,对该工程仿自然型鱼道进、出口的布置提供了推荐方案,为较大水头仿自然型鱼道进、出口的布置研究提供参考。Nature-like fishway effectively mitigates the impacts of hydraulic project construction on fishes.The flow condition at fishway＇ s entrance and exit directly affects its application result.We analyzed the construction and research status of nature-like fishway in China and abroad.Through integral nature-like fishway model experiment and live fish＇ s upstreaming experiment,we researched the flow regime,velocity distribution and other hydraulic parameters of the fishway＇ s entrance and exit under different operation modes of power plant,and proposed a recommendation layout of nature-like fishway＇ s entrance and exit.This research could be a reference for the design of natural-like fishway＇ s entrance and exit layout under large working head.
