株洲枢纽隔板式鱼道设计

Design of diaphragm plate fishway of Zhuzhou junction

为消除枢纽大坝对鱼类造成的不利影响,改善流域鱼类的栖息环境,恢复鱼类资源多样性及稳定性,需要科学设计过鱼设施、为鱼类提供洄游通道。隔板式鱼道作为普遍选用的过鱼设施形式,具有节能、结构稳定、占地少、连续过鱼等优点,但由于其结构复杂,设计难度较大。结合国外鱼道设计研究成果和国内类似工程实际经验,以株洲枢纽鱼道为背景,详述隔板式鱼道的设计要点,具体包括鱼道运行水位、设计水流速度、槽身尺寸等重要参数的设计,可为类似工程提供参考。

To eliminate the adverse effects of the dam on fish,improve the habitat environment of fish in the river basin and restore the diversity and stability of fish resources,it is necessary to design fishing facilities scientifically to provide migration passages for fish.Diaphragm plate fishway,as a commonly used type of fishing facilities,has the advantages of energy conservation,stable structure,less land occupation,continuous passing,etc.However,it is difficult to design because of its complex structure.Combining with referring to the research results of fishway design abroad and the practical experience of similar projects in China,taking the fishway of Zhuzhou junction engineering as the background,we elaborate the key points of general layout design of diaphragm plate fishway,including the selection of important parameters such as the operating water stages,design discharge velocity and groove design,which can provide references for similar projects.
