摘　　要：在某拟建高坝水库集鱼设施进行优化设计时,采用水深平均二维水动力模型分别对集鱼系统原设计方案和优化设计方案进行模拟,根据水动力结果对两种设计方案进行过鱼效果评估,并优选方案。结果表明,设计双闸门和改进溢流堰位置及调节流量增大了进鱼口有效宽度;修正进鱼口的设计减缓了流速突增现象,提高了洄游鱼类通过率。In order to optimize the design of the fish-gathering facility of a high dam reservoir,the original design scheme and the optimal design scheme of the fish-gathering system were simulated by using two-dimensional hydrodynamic model of average depth.The design of double gate and overflow weir location improvement and flow regulation increase the effective width of the inlet.The inlet design correction reduces the flow rate surge phenomenon and improves the passing rate of migratory fish.
