受地形限制,双河水库溢洪道进口段形式较为复杂,致使控制段横向水深分布极为不均、泄槽段出现明显菱形冲击波及横向水面差。为改善溢洪道的水流流态,对进口导墙布置及控制段闸墩体型进行局部修改。修改后,控制段及泄槽水流流态得到了明显改善。试验成果对类似的工程设计具有参考借鉴意义。
受地形限製,雙河水庫溢洪道進口段形式較為複雜,緻使控製段橫嚮水深分佈極為不均、洩槽段齣現明顯蔆形遲擊波及橫嚮水麵差。為改善溢洪道的水流流態,對進口導牆佈置及控製段閘墩體型進行跼部脩改。脩改後,控製段及洩槽水流流態得到瞭明顯改善。試驗成果對類似的工程設計具有參攷藉鑒意義。

The terrain conditions, reservoir spillway inlet forms are more complex, so that the control section of lateral depth distribution is extremely uneven, chute appeared in diamond shock wave and transverse water difference. In order to improve the spillway flow pattern, on the import of guide wall arrangement and control section of pier body size by partial modification, modification, control section and the chute flow pattern improved. The test results of the design to similar works has reference significance.
