摘　　要：面对供水管网密集度高、体量大、管龄长等特征,同时因地下管网的复杂性使得供水管网的改造和维修带来巨大挑战,越来越多的管道在超龄和受损状态下运行,给城市安全带来隐患。以往的供水管线评估模型多使用单纯的爆管事故统计数据来评价管道事故,而统计量的限制不足以用来对管网进行全面风险评估。近年来,供水管道带压带流内检测技术愈趋成熟,而基于此检测方法的管道运行状态评估方法尚未统一。文章在采用管道内检测机器人对上海市中心城区的老旧、隐患管网进行内窥检测的基础上,借鉴排水管道评估的方法,以管道内实际的可视化检测成果半定量风险评价方法分析管段缺陷,提出了针对城镇供水管网中某一特定管段运行状态评估、量化管道风险的方法,对管道风险进行预判和控制,并对某一管段进行了实例评估。文章提出的供水管道运行状态的半精确评估方法有助于供水企业准确掌握供水管网运行状态,一定条件下可推广应用,未来还可借助其他检测手段对评估结果进行交叉验证和多数据融合分析,同时可建立供水管道动态风险评估模型,以实现安全风险的实时预警。Given the high density,large volume,and aging of water supply networks,along with the complexity of underground pipe networks,the transformation and maintenance of water supply networks present significant challenges.The increasing number of aging and damaged pipelines poses hidden risks to urban safety.Previous evaluation models for water supply pipelines often relied on statistical data of pipe burst accidents,which had limitations in assessing the comprehensive risk of the pipeline network.In recent years,pressurized detection technology for water supply pipelines has become more mature,but there was no unified evaluation method for assessing the operational state of pipelines based on this detection method.This study drew on the method of evaluating drainage pipelines and applied it to the endoscopic detection of old and concealed pipeline networks in the central urban area of Shanghai,using pipeline inspection robots.The study analyzed pipeline defects through semi-quantitative risk assessment based on actual visual inspection results.It proposed a method to evaluate the operational status of specific sections in the urban water supply network and quantify pipeline risks.An example of evaluating a particular pipeline section was provided.The accurate evaluation method for water supply pipeline operational status presented in this study helps water supply enterprises accurately understand the operational state of their pipeline networks.Under specific conditions,this method can be popularized and applied.In the future,other monitoring and detection methods can be used to validate the evaluation results,and multi-data fusion analysis can be conducted.Additionally,a dynamic risk assessment model for water supply pipelines can be established to enable real-time early warning of safety risks.
