摘要
废黄河是一条多泥沙河流,通榆河与废黄河在滨海县内交汇处的地涵于1999年建成投运至今,必然对其上下游河道的冲淤变化产生影响。基于工程运行后的地涵上下游引河段河床地形实测资料,分析地涵上下游河段冲淤量和河道断面形态变化,总结河道冲淤变化原因,提出减淤措施。结果表明,地涵的建设和运行导致其上下游河道水动力发生变化,河槽明显淤积,河槽过水面积普遍减小。
The Abandoned Yellow River is a multi-sediment river. At the intersection of Tongyu River and Abandoned Yellow River in Binhai County, the underground culvert was built in 1999 and put into operation so far, which must have an impact on the erosion and siltation of its upstream and downstream river. Based on the measured data of riverbed topography after the project being operated, the changes of the erosion and siltation quantity of the upstream and downstream underground culvert and the channel section were analyzed, the reason of erosion and siltation was summarized, and sedimentation reduction measures were proposed. The results showed that the construction and operation of the culvert lead to the hydrodynamic changes of the upstream and downstream river, obvious siltation of the river channel and general decrease of river channel area.
