北运河榆林庄闸至杨洼闸段综合治理工程模型试验研究

River model test and research on comprehensive control project of Beiyun river channel from Yulinzhuang sluice to Yangwa sluice

运用物理模型试验,对实施北运河榆林庄闸至杨洼闸段综合治理工程前后河道的行洪变化进行研究分析。给出各工况下河道的沿程水面线,分析流势流速变化规律,确定河道险工段。分析河道整治方案相关工程措施的效果,明确延芳淀湿地工程对河道行洪的影响。

Based on the fixed bed river model test, the change of flood discharge before and after the implementation of the comprehensive treatment project of Beiyun river channel from Yulinzhuang sluice to Yangwa sluice is studied and analyzed. The water surface curve of each test scene is given; the change rule of the flow velocity is analyzed; and the sections easily scoured of the main channel are determined. The paper not only analyzed the effect of engineering measures related to river regulation programs but also clarified the impact of Yanfangdian wetland project on flood discharge.
