摘要
本文进行了清河闸应急除险加固工程水工模型试验的研究,通过33组次的定床、动床模型实验,测量了特征流量下包括水面线、流速大小及分布、压力大小及分布和冲刷范围及深度等在内的水力要素,验证了清河闸的泄流能力,评价分析了各种泄流条件下泄流量对下游海漫及防冲槽的影响。实验成果可供工程设计和水闸运行管理等相关部门参考。
This paper studied the Qing River Sluice emergency reinforcement project hydraulic model test by 33 groups times stable bed,moving bed model experiment,measuring the water line,the flow rate characteris-tics of size and distribution,including lower flow rate,pressure and size distribution and hydraulic erosion factors,including the scope and depth,verify the clear Sluice discharge capacity,evaluation and analysis of the effects of various discharge conditions discharged downstream flow and scour the sea diffuse slot.The experimental results of operation for the engineering design and sluice management and other related departments provides reference.
