| 摘 要： | 供水管网漏失的监测难度大,维护费用高.为了有效减少管网漏失率,需要研发管网漏失模型,从而制定合理的监测模式和维护方案.针对管网老化过程,分析了其与管网漏失率的关系,应用决策树方法开发了包含管龄和管径两个因素在内的漏失规律模型.以北京市为例,对主城区19年间(1987年-2005年)由供水管网老化造成的漏失数据进行分析.结果表明,老化漏失管道的管龄服从Weibull分布,管龄为20年左右的管道更易产生漏失.利用建立的漏失规律模型,通过ArcGIS预测了2008年北京市区供水管网的老化漏失分布情况,其结果将用于漏失监测仪的优化布置.

| Abstract: | The leakage from water supply pipe network is difficultly detected and has high maintenance cost.In order to reduce the leakage rate of water supply pipe network,it is necessary to develop a model for leakage from water supply pipe network to establish a reasonable monitoring mode and a maintenance scheme.According to the aging process,the relation between the aging and the leakage rate was analyzed.Decision tree method was applied to develop a rule-based leakage model combining the factors of pipe age and ... |
