依据北方某城市供水管网2006年—2008年的爆管数据,以ArcGIS 9.2为软件平台建立了供水管网爆管数据库,并提出了两种供水管网爆管空间分析方法,分别建立了供水管网爆管的空间叠置分析模型和缓冲区分析模型。由空间叠置分析结果可确定供水管网发生爆管可能性的空间分布;而由缓冲区分析结果可知,供水管网爆管的发生具有空间积聚性。
According to the burst data of a city water supply pipe network in northern China from 2006 to 2008, ArcGIS 9.2 software platform was used to establish the pipe burst database of water supply pipe network. Two spatial analysis methods of pipe burst pipe network were proposed, and the water supply Spatial Overlay Analysis Model and Buffer Analysis Model of Pipe Network. Spatial overlay analysis results can be used to determine the spatial distribution of possibility of squibing in water supply network. From the results of buffer analysis, it can be seen that the squib of water supply pipe network has spatial accumulation.
