溃坝及洪水演进数值模拟研究
Digital Simulation of Dam-break and Flood Flow
【摘要】 溃坝洪水计算包括溃坝模拟及洪水演进模拟两部分。为避免复杂公式推导及求解,对溃坝模拟,采用简化模型,对二维洪水演进模拟,采用有限体积法进行求解,引入通度系数模拟计算区内部的阻水建筑物。采用GIS技术实现了洪水演进动态演示功能。
【Abstract】 Calculation of dam-break flood includes dam-break simulation and flood flow simulation.In order to avoid complex formulas,a simplified model is adopted for dam-break simulation.Two-dimensional dam-break flood flow simulation program is developed independently based on finite volume method.Partial cell parameter is introduced to simulate the blocks in the inundation area.Dynamic demo of flood flow is implemented by GIS.
