摘要
城市雨水管网是重要的城市基础设施,担负着收集雨水、及时排除市区和流经市区雨水的任务。随着城市的发展,区域不透水面积增加,降雨造成淹水现象较为普遍。当大强度降雨时,造成排水管网压力过大,雨水无法及时排走,在城区低洼处形成积水,严重影响城市交通和居民生活。本文利用GIS对空间数据的处理和分析功能,结合SWMM模型,建立雨水管网达标规划GIS系统,实现雨水管网设备的属性数据及空间数据的一体化管理,为城市暴雨积水计算提供可视化分析的手段。
The rainwater pipe network in city is an important urban infrastructure.It can promptly eliminate the rainwater in city.With the development of city,regional impervious area has increased and then the precipitation always caused flooding in city.When the precipitation is more in city,it always cause the rainwater pipe network is not enough to be used.And the rainfall cannot be cleaned out.The wa ter is accumulated in the low elevation area in city.It will have the serious influence on the traffic and people’s life in city.This paper combined spatial analysis function in GIS with SWMM model to establish rainwater pipes network system based on GIS technology.In this system,we realized the integration management of attribute data and spatial data in rainwater pipes network.It will provide the way of visualization analysis for calculating storm water in city.
