红花水电站第一年枯水期施工导流模型试验研究

First dry-period construction diversion model test for Honghua Hydropower Station

建立红花水电站施工导流物理模型,对红花水电站第一年枯水期的施工导流方案进行试验研究,优化了该阶段左右岸挡水围堰的施工顺序和明渠开挖方案,使导流明渠满足度汛和通航的要求,并减少了第一年枯水期施工导流方案的工程量。

Physical model was constructed to test and study the first dry-period construction diversion scheme for Honghua Hydropower Station. Based on the testing results, the construction programs of left and right water retaining cofferdams as well as the open channel excavation scheme were optimized, which not only renders less construction quantities, but also lead to the diversion open channel meet requirements for flood relief and navigation simultaneously.
