摘要
在山区河流上修建涉水工程需考虑其对河道水流特性的影响,而山区河流水流运动的复杂性使此研究变得较为困难。该文建立了基于非结构网格的平面二维水流运动数学模型,并验证了其可靠性。采用该模型对岷江河段模拟计算,计算结果表明河段上拟建大桥的存在对河段水流特性无明显影响。
The effect of water related project on flow characteristics must be considered while the project built on the mountain rivers and the complex of flow characteristics makes the research to be in difficult situation.A 2-D flow numerical model based on unstructured grids has been built and tested.The model is adopted to simulate flow in the Min River and the simulation results show that the effect of built bridge on flow characteristics is unconspicuous.
