摘要
地下供水管网的爆漏事故频频发生,探寻诱发事故的主因,并有针对性地预测、控制此类事故已成为各级水务部门急需解决的重要问题。整理北方某市供水管网2000—2008年的管道维修记录数据,运用统计分析法提取供水管网爆漏事故的典型影响因素。引进等级评分与因素权重量化不同因素对爆管的影响程度,采用GIS的空间分析技术,以空间建模的概念化模式研究一个单目标、多准则的空间预测问题,最后基于此对供水管网建立爆管评价模型,评价分析供水管道爆管的等级。
As underground water supply pipe network explosions occurred frequently,exploring the main cause of suchaccident for the prevention and control has become an important issue for water resources administration departmentsat all levels. This article arranges data from maintenance records of water pipes in a northern urban water supply network during 2000～2008. Typical influencing factors of water pipe breaks were extracted by using statistical analysis method. Rating scale and weights of factors were introduced to quantify influence degree of different factors to pipe breaks. With the tech-nology of GIS spatial analysis,a single-objective and multi-attribute problem of spatial prediction was studied by using a conceptualization mode of spatial modeling. At last,evaluation modelof water pipe breaks for water supply network was establisheded to evaluate and analyze the grade of water pipe breaks.
