摘要
文中洪水分析采用MIKE ZERO系列洪水模拟软件。其中:采用一维非恒定流模型模拟河道洪水演进过程;采用美国国家气象局DAMBRK方法计算溃堤洪水;采用二维非恒定流模型模拟淹没区的洪水演进过程。将河道一维非恒定流模型、溃堤模型和淹没区二维非恒定流模型相互耦合、联立求解,以模拟堤防溃决对防洪保护区的影响。经验证,模拟结果与调查资料基本符合。
In this paper, the flood is analyzed by the series of flood simulation software of MIKE ZERO. The one-dimensional unsteady flow model is used to simulate the evolution of river flood, the DAMBRK method of the National Weather Service is used to calculate the dike burst flood and the two-dimensional unsteady flow model is used to simulate the process of flood routing in the inundated area. The influence of dike burst on flood control protection zone is simulated by the model coupling and Simultaneous solving with one-dimensional unsteady flow model, dike burst model and the two dimensional unsteady flow model of inundated area. After verification, the simulation result is basically accord with the survey data.
