摘　　要：为解决西藏扎拉水电站工程设计中过鱼设施的比选、鱼道进出口位置的合理选择及鱼道结构型式的确定这三大工程设计技术难点,重点分析了过鱼设施比选的思路和方法,针对鱼类的趋流特性、克流能力等生物学特性,结合物理模型试验研究成果,对鱼道总体布置、进口、出口、主体段以及附属建筑物等进行了合理设计,创新性地提出鱼道布置采用单道折叠+双道层叠+隧洞+单道的型式。该鱼道总体布置型式为国内首次采用。扎拉水电站鱼道的建成,对高山峡谷中,中高水头水电站鱼道总体设计具有一定参考价值。In order to solve the engineering design difficulties in the selection of fish passage facilities,the reasona-ble choice of fish passage import and export location and the determination of fish passage structure type of Xizang Zhala Hydropower Station was analyzed.We focused on the analysis of the fish passage facilities selection ideas and methods,the fish flow characteristics,the ability to grasp the flow and other biological characteristics,combined with the physical model test research results,the overall layout of the fish passage,inlet,outlet,main section and ancillary buildings,etc,were reasonably designed.The innovative proposal of single fold+double laminated+tunnel+single type of fish passage layout was adopted for the first time.The completion of Zhala Hydropower Station fish passage can provide a reference for the overall design of fish passage in high mountain valley or medium and high head hydropower station.
