金沟河引水枢纽除险加固工程水工模型试验探讨

Discussion on Hydraulic Model Test of Danger Removal andReinforcement Project of Jingou River Diversion Project

对不同频率洪水工况下金沟河引水枢纽除险加固工程进行水工模型设计及试验研究,具体包括引水分流试验、泄洪试验、设计洪水流速试验和输沙试验。试验成果表明:在不同流量情况下,引水渠到符合设计流量泄流要求,且通过泄洪闸的合理调度,能防止泥沙进入引水渠,并快速排沙。结论可为金沟河引水枢纽除险加固工程以及同类型分洪建筑物多、泄流情况复杂的工程除险方案设计提供参考。

In this paper,the hydraulic model design and experimental research of the Jingou River Diversion Project under different frequency flood conditions are carried out.This research specifically includes water diversion flow test,flood discharge test,design flood velocity test and sediment transport test.The test results show that the diversion channel meets the design flow discharge requirements under different flow conditions.Moreover,the reasonable dispatch of the flood gate can prevent the sediment from entering the diversion channel and quickly discharge the sand.The conclusion can provide a reference for the design of the danger elimination and reinforcement project of the Jingou River Diversion Project and the design of the engineering elimination scheme with many flood diversion structures of the same type and complicated discharge conditions.
