| 摘 要： | 在南昌市排水管网信息的基础上,研制了城市积涝的仿真模型。模型以平面二维非恒定流的基本方程和无结构不规划网格划分技术为骨架,结合一维非恒定流方程的算法,建立了南昌市城市内涝仿真模拟系统。以2003年6月一次特大暴雨过程的模拟,取得较好效果,模拟的积水网格中,误差基本在20cm以内,预报结果能满足市政排水部门的要求。

| Abstract: | Based on the information from the drainage network in Nanchang, a model is developed to simulate the urban flooding, which is framed with the basic equation of unsteady flow and the unstructured unplanned gridding on the 2D plane and incorporated with the calculation of the equation of 1D unsteady flow. The process of an extra large storm in June 2003 was simulated to achieve good results. The simulated flooding has a tolerance within 20 cm, and the precast result can satisfy the requirements of the municip... |
