摘　　要：以湘江大源渡枢纽扩建鱼道工程为例,论述在已建航电枢纽中扩建鱼道工程需考虑的几大设计难题。重点分析了过鱼对象及时段、运行水位及进出口高程、设计流速、结构形式选择、进出口布置等的确定思路及方法。分析认为:湘江过鱼对象主要为"四大家鱼";鱼道设计流速0. 2～1. 3 m/s更有利于过鱼;进口布置是鱼道设计的关键,适当考虑诱鱼可增强过鱼效果;鱼道工程考虑与扩建船闸工程协同设计。总结了在实际地形及已有建筑物等限制因素下的鱼道工程设计经验,对类似工程具有重要借鉴意义。Based on enlarged fishway construction of Dayuandu navigation & hydropower complex in Xiangjiang River,we discuss several design problems that should be considered in enlarged fishway construction on constructing or constructed navigation & hydropower complex.The thoughts and methods to determine the fish migrating objects and time,the operation water levels,elevations of fishway inlet and outlet,the fishway design velocity,the fishway structure type,and the layout of fishway entrance and outlet have been analyzed emphatically.Analyses show that four famous domestic fishes are the mainly fish migrating objects in Xiangjiang river;the design velocity of fishway is 0.2~1.3 m/s,which is more favorable for fish migrating;the key to the fishway design is the layout of the inlet,thus,proper consideration of attracting fish can enhance the effect of fish migrating;the fishway project should be considered in conjunction with enlarged lock construction.This paper summarizes the experience of fishway design under limited factors such as actual topography and existing buildings,which can have some reference significance for similar projects.
