【摘要】：黄金峡水利枢纽鱼道的最高运行水头为45.50 m,上游水位的变化幅度达10 m,属于高水头过鱼建筑物。根据过鱼对象的种类、习性和游泳能力,过鱼建筑物选用带同侧竖缝式隔板的"U"型槽式鱼道,并通过水力学计算得出了鱼道池室的结构尺寸,同时为适应上游水位的变化,鱼道布置了5个出鱼口。为了分析鱼道布置方案的合理性,建立鱼道进口、集鱼系统整体模型和鱼道局部模型,模拟得出了鱼道进鱼口周边区域的流速分布、过鱼池水力学特性等。试验结果表明,鱼道进鱼口区域的流场分布适宜鱼类上溯至进鱼口,过鱼池的水力学条件满足符合过鱼对象顺利上溯的要求,设计方案是合理的。
[Abstract]:The maximum operating head of the fishway is 45.50 m, and the change range of the upstream water level is 10 m, which belongs to the overfishing structure with high water head. According to the species, habit and swimming ability of the fish passing object, the fish crossing building adopts the "U" slot fish tunnel with the same side vertical seams. The structural size of the fish tunnel chamber is calculated by hydraulics, and in order to adapt to the change of the upstream water level, the structure size of the fish tunnel chamber is obtained by hydraulic calculation in order to adapt to the change of the upstream water level. There are five fish exits in the fishway. In order to analyze the reasonableness of the fish tunnel layout, the fish channel inlet, the fish collecting system integral model and the fish tunnel local model were established. The velocity distribution around the fish entrance and the hydraulic characteristics of the fish pond were obtained by simulation. The experimental results show that the distribution of the flow field in the fish entrance area is suitable for the fish to go up to the fish inlet, and the hydraulic conditions of the fish pond meet the requirements of the fish object tracing smoothly, and the design scheme is reasonable.
