灌河燕尾港2万吨级码头防洪影响潮流数模研究

Study on influence of Yanweigang 20000 t terminal by Guanhe River on flood control using numerical simulation of tidal current

为了研究大型涉水建筑物的修建对潮汐河段防洪的影响,以灌河燕尾港2万吨级码头防洪影响为研究内容,采用有限体积方法,建立三角形非结构网格二维潮流数学模型,分析码头建设前后工程区水位、流速和流场的变化。结果表明,码头兴建后对工程区河道的水位和流速影响均较小,流场变化局限在局部小范围地区,故对灌河的防洪影响较小。

In order to study the influence of large - scale water related building on flood control of the tidal reaches, taking the Yanweigang 20000 t terminal by Guanhe River as an example, the two - dimensional triangular unstructured grid numerical model is established using finite - volume method. The variation of water level, flow velocity and flow field in the project area before and after the construction is analyzed. The results show that the influence of the terminal on the water level and flow velocity in the project area is little, and the changes of flow field are restricted in small areas, so the influence on the flood control of Guanhe River is little as well.
