高坝集运鱼系统模型试验研究

Model Test Study of Fish Collecting and Transporting System in High Dams

结合某水利枢纽工程,进行了集运鱼系统模型试验研究。分析了过鱼设施参数,详细介绍了集鱼系统的设计研究,建立了集鱼系统物理模型和设计工况,对集鱼廊道和补水廊道流态及流速进行了水工模型试验验证。结果表明集鱼系统在工况3~8下满足过鱼流速范围0.35~0.74 m/s,针对工况1~2进行优化设计,布置辅助诱鱼措施和补水措施,提高集鱼效果。

A model test study on the fish collecting and transporting system was conducted in conjunction with a certain water conservancy hub project.The parameters of the fish transportation facilities were analyzed.The design and research of the fish collecting system were introduced in detail.A physical model and design conditions of the fish collecting system were established.Hydraulic model tests were conducted to verify the flow pattern and velocity of the fish collecting gallery and water replenishment gallery.The results show that the fish collecting system meets the flow rate range of 0.35~0.74 m/s under operating condition 3~8.Optimization design was carried out for operating conditions 1~2,and auxiliary fish lure measures and water replenishment measures were arranged to improve the fish collection effect.
