MIKE FLOOD模型应用于南昌排水防涝综合规划

Application of MIKE FLOOD Model in Comprehensive Planning of Drainage and Waterlogging Prevention in Nanchang City

以DHI公司开发的MIKE FLOOD水力软件为工具,实现了城市管网、河道及二维地形的耦合模拟,完成了南昌市排水防涝综合规划的设计任务。结合此次规划,指出在软件的具体应用中应注意的若干问题并提出解决方法,包括排涝区域的划分、模型的概化、汇水面积的划分、雨型及标准的选择、全局与局部的结合、评价方法的选择及改造措施的原则,为今后的规划设计工作提供了一定的借鉴。

Coupled simulation of city pipe networks, rivers and two-dimensional topography was a- chieved by taking MIKE FLOOD hydraulic design software of DHI company as the tool. The design task of comprehensive planning of drainage and waterlogging prevention in Nanchang City was completed. Combined with this planning, a number of issues which should be pay attention to in the specific applica- tion of software were pointed out and solutions were also proposed, including the division of drainage are- as, the model generalization and the division of catchment areas, the selection of rainfall pattern and standard, the combination of global and local considerations, the selection of evaluation methods and the principle of reform measures, in order to provide reference for the planning and design work in the future.
