摘要:
以河口未建挡潮闸的苏北灌河为研究对象,在河口两处位置分别设置假想闸门,利用MIKE 21建立灌河及外海的潮流数值模型,研究了闸门建设位置及闸门调度方式对闸下冲淤效果的影响。结果表明,闸门启闭时的上下游水位差、闸门建设位置和泥沙特性对冲淤效果有决定性影响,在大潮期间进行纳潮冲淤能够取得更优的效果。但是,纳潮冲淤期间存在闸上淤积的风险,因此有必要联合多种清淤手段同时清淤。
Abstract:
This study focuses on the Guan River in the northern Jiangsu province, where tidal gates have not yet been constructed. Two hypothetical gates are placed at different locations in the estuary. The numerical model of tidal flow in Guan River and the open sea was established by MIKE 21, and the influence of the gate construction location and the gate scheduling methods on the effectiveness of alleviating downstream sediment were investigated. The results indicate that the water level difference during the gate scheduling process, gate construction location, and sediment characteristics have a decisive impact on the dredging effect. Conducting silt washing by tide during high tide periods can achieve better results. However, there is a risk of upstream sedimentation of the gate during the process, it is necessary to combine multiple methods of desilting at the same time.
