本文在大比尺鱼道模型中对同侧竖缝式鱼道的水力特性进行了系统的试验研究,并做了放鱼试验。选择了5组典型流量,对每一组流量系统地实测了13h(h为相应流量的水深)平面、12h平面及23h平面各断面(x=0,10,20,30,40,50,60,70,80,90,100cm)的流速分布,分析了同侧竖缝式鱼道的流速分布形态、无量纲流速分布特征、断面最大流速沿程衰减情况、同一水深不同流量的流速分布。通过放鱼试验,考察了鱼类对不同流量的响应情况,提出同侧竖缝式鱼道的不足及其改进措施。
In this paper, the hydraulic characteristics of the ipsilateral vertical slot fishway in a large scale fishway model were systematically studied and tested. Five typical sets of flow rates were selected and systematically measured for each set of flows for 13h (h is the depth of the corresponding flow), 12h and 23h (x = 0, 10, 20, 30, 40, 50, 60 , 70,80,90 and 100 cm). The distribution of flow velocity, dimensionless flow velocity distribution, the attenuation along the maximum flow velocity and the flow velocity distribution at the same water depth and depth were analyzed. Through the fish-drop experiment, the response of fish to different flow rates was investigated, and the deficiency of the same-side vertical slot fish and its improvement measures were proposed.
