| 摘 要： | 通过非结构网格建立了长江感潮河段二维潮流数学模型,研究了水工建筑物在非结构网格中的处理,验证结果良好;为检验模型长河段沿程流量的守恒性,模型上边界分别采用枯水、中水、洪水3种恒定流量模拟感潮河段水流运动。计算结果表明:模型沿程流量守恒性良好,模型能够有效模拟长江感潮河段水流运动。

| Abstract: | Two-dimensional tidal numerical model of tidal river in Yangtze River is built with unstructured grid, and the generalization of hydraulic structures is discussed to get precise result. Three tidal numerical models with different boundary condition (dry, water, flood) are built to test the conversation of flow, and the results indicate that the flow conversation of the tidal numerical model is favorable. In short, the tidal numerical model can simulate the tidal current effectively. |
