摘要
为探索适应多变幅水位条件下鱼类洄游要求的多流态鱼道池室结构,以赣江象山枢纽鱼道为研究对象,采用三维数值模拟和物理模型试验的方法,将传统竖缝式鱼道隔板调整为孔板溢流结构,对鱼道池室水力特性进行研究。结果表明:在低水位运行时,竖缝溢流式鱼道为单一竖缝结构,满足该河段低水鱼类要求;物理模型试验中,在高水位运行时,竖缝整体流速为0.8~1.2 m/s,溢流孔流速为0.8~0.9 m/s,同时满足不同水深鱼类过流要求。研究成果可为类似竖缝式鱼道设计提供参考。
In order to explore the fishway chamber structure suitable for the migratory requirements of different water depths,this paper takes the fishway of Xiangshan hub in Ganjiang River as the research object,adjusts the traditional vertical joint fishway partition board into a hole plate overflow structure,and adopts the method of dimensional numerical simulation and physical model test to study the flow characteristics of the fishway chamber.The results show that at low water level operation,the vertical joint overflow way is a single vertical joint structure,which meets the requirements of low water depth fish in this river section.At high water level operation of physical model tests,the overall flow velocity of vertical joint was between 0.8 m/s to 1.2 m/s,and the overflow hole flow velocity is between 0.8 m/s to 0.9 m/s,which meets the requirements of fish passage at different water depths.The research results can provide a reference for the design of fishway.
