摘　　要：为了减缓龙塘大坝枢纽改造工程对南渡江鱼类洄游的不利影响,通过建设龙塘大坝鱼道,有效减缓龙塘大坝工程对南渡江上下游的阻隔影响,提升南渡江河流连通性。现对海口市南渡江龙塘大坝枢纽改造工程鱼道设计进行研究,介绍龙塘大坝鱼道的设计及试验过程,内容主要包括南渡江龙塘大坝枢纽主要过鱼种类的游泳能力试验、游泳能力指标在鱼道设计中的应用、鱼道局部数学模型、鱼道局部物理模型、优化设计及放鱼试验等6个方面,可供其他过鱼设施设计参考。In order to mitigate the adverse effects of the Longtang Dam renovation project on the migration of fish in the Nandu River,the construction of fishway effectively reduces the obstruction impact of the dam on the upstream and downstream sections of the Nandu River and enhances the river connectivity.This paper investigates the design of the fishway of Longtang Dam renovation project on the Nandu River in Haikou City.It introduces the design and test process of the Longtang Dam fishway,including the swimming ability test of main fish species in Nandu River,the application of swimming ability index in fishway design,local mathematical model of fishway,local physical model of fishway,optimized design and fish release test.The research results can be used as reference for the design of other fishway facilities.
