摘要: 为研究拟建州河大桥对桥区河段水动力特性的影响,通过建立非恒定流二维水动力模型,模拟了建桥后桥区 河段的水流条件并分析了建桥前后桥区河段流场的变化情况。结果表明: 建桥后桥区河段水流流场变化较小,水 流条件较为理想。

关键词: 州河大桥, 非恒定流, 二维水动力数学模型, 有限元

Abstract: In order to analyze the impact of new Zhouhe Bridge to the hydrodynamic characteristics of this river reach,the unsteady flow two-dimension hydrodynamic model is developed. The flow condition of the river reach after the bridge's finish is simulated and the change of the river reach flow field before and after bridge's finish is analyzed. The result shows that the change of the river reach flow field is quite small and the flow conditions are quite ideal after the bridge is built.

Key words: Zhouhe Bridge, unsteady flow, 2-D hydrodynamic numerical model, finite element method
