基于水动力数学模型的中顺大围群闸联动调度模拟研究

Research on the Linkage Dispatching Simulation of Zhongshun Dawei Group Gate Based on Hydrodynamic Mathematical Model

通过建立一个以珠江三角洲网河区作为整体,嵌套中顺大围等主要堤围内河涌的一维水动力模型,对中山市主要堤围内外各主要节点水位、流量进行模拟分析,通过对平、枯两种水文条件,不同闸门引排方式,不同河涌控制水位等多种方案进行比较,提出群闸联调方案,优化调整现有排涝布局,加强内河涌和外江水道的连通,利用群闸联控措施改善中顺大围水环境。

By establishing a one-dimensional hydrodynamic model with the Pearl River Delta network as a whole and nesting in the main dikes such as Zhongshun Dawei,the water level and flow of the main nodes inside and outside the main dikes in Zhongshan City are simulated and analyzed.Comparing three kinds of hydrological conditions,such as different gate guidance and drainage methods,and different river gushing control water levels,etc.,the group gate joint adjustment scheme is proposed,the existing flood control layout is optimized and adjusted,and the inland river gushing and the outer river watercourse are strengthened.Unicom,using the group gate joint control measures to improve the water environment.
