| 摘 要： | 采用无结构网格的有限体积法二维数学模型,模拟浙江省丽水市开潭水利枢纽工程建设对上游铁路大桥行洪的影响。根据河流的特点,采用四边形和三角形混合网格剖分,并耦合过闸的水力计算,对方程联立求解。结果表明该模型能较好地模拟河道的水流特性和涉水工程建设后的影响,成果为管理部门决策提供了依据。

| Abstract: | The two-dimensional mathematical model for the finite volume method on unstructured meshes was used for simulating the influence of flood discharge by the Kaitan Hydro Project on the upper railway bridge.According to the characteristics of rivers,the triangular and quadrangular hybrid meshes were employed for hydraulic calculation of lockage water flow.The calculated results by solving the simultaneous equations show that the model can effectively simulate the water flow characteristics and the effects of hydraulic structures and provide a basis for management departments to make decisions. |
