SWMM模型在低洼积水工程的应用

Low-lying water treatment based on SWMM

现在大多数中小型设计院都是按照规范及经验对区域排水系统中的现有问题进行改建设计,具体效果无法有一个准确的定量分析,难以用具体的数据来解释改善之后能达到的效果,而SWMM与ArcGIS作为免费的软件可解决上述缺陷。利用SWMM(storm water management model)与ArcGIS结合,以及MIKE等软件模型模拟区域排水系统的运行现状,分析得出现有管网的"瓶颈制约",进而提出改造方案来缓减节点溢流和管道过载的情况。提示通过模型的建立为城市排水管网改建和设计提供了技术支持,具有理论指导意义。

Now in most of the small and medium-sized design institutes,reform design to problems in regional drainage system is according to the stadard and experiences,but the specific effect cannot be expressed by an accurate estimate which need to explain to the stakeholders.However with the help of geographic information system（ArcGIS）and storm water management mode（SWMM）,we can solve this problem.By geographic information system（ArcGIS）and storm water management model（SWMM）or MIKE,the running condition of the rain pipe system is simulated to find out the＂bottleneck＂of the pipe network.Based on that,we put forward reform project to ease the condition of the node flooding and conduit surcharge.Supporting by this technology,the result can be applied to optimize the design and reconstruction of urban drainage network.
