【摘要】：為了恢復豐滿水電站魚類洄游通道,在豐滿水電站重建工程壩址處設置升魚機和魚道。豐滿重建工程升魚機具有所處河道寬,發(fā)電機組運行工況復雜、下游水深淺等特點,魚類尋找升魚機入口具有較大的難度。為提高升魚機運行效率,通過數(shù)值模擬開展了升魚機進魚口水流條件改善措施的專項研究。模擬結(jié)果表明,在機組流量1 170 m3/s、圍堰上游主要開挖至187 m、局部區(qū)域開挖至186m、圍堰及下游區(qū)域局部開挖至187 m的條件下,三臺及三臺以下機組同時運行時,河道大部分區(qū)域流速均小于1.2 m/s,魚類能進入集魚系統(tǒng)進魚口。成果顯示,文中提出的電站運行方式及下游河道開挖方案能為電站魚類上溯提供順暢的洄游通道。
[Abstract]:In order to restore the fish migration channel of Fengman Hydropower Station, a fish hoist and a fish tunnel are set up at the site of the reconstruction project of Fengman Hydropower Station. It is difficult for fish to find the entrance of fish hoist because of its wide channel, complex operating conditions and shallow downstream water. In order to improve the operating efficiency of the fish hoist, a special study was carried out on the improvement of the water flow conditions at the fish inlet of the fish lifter by numerical simulation. The simulation results show that under the conditions of unit flow rate of 1,170 m3 / s, the upstream of the cofferdam is mainly excavated to 187 m, the local area is excavated to 186m, and the cofferdam and downstream area are excavated to 187 m, when three or less units operate simultaneously, The flow velocity in most areas of the river is less than 1.2 m / s, and fish can enter the fish-collecting system. The results show that the proposed operation mode and the downstream channel excavation scheme can provide a smooth migration channel for the upstream fish in the power station.
