通过水工模型试验对莲麓水电站导流明渠过流能力,施工桥对水位的壅高以及水流对施工桥安全影响进行了研究。试验结果表明,通过优化导流明渠出口方案后,采用在施工桥左侧再开挖一条渠道进行分流的工程措施,有效地改善了导流明渠出水口及下游河道的水流条件,满足了设计要求。 Through the hydraulic model test, the over-flow capacity of the diversion channel at Lianlu Hydropower Station, the high water level of the construction bridge and the impact of water flow on the construction bridge safety were studied. The test results show that by optimizing the outlet scheme of diversion open channel, engineering measures of re-excavation of a channel on the left side of the construction bridge are adopted to effectively improve the water flow conditions at the outlet of the diversion channel and the downstream channel to meet the design requirements .
