摘要
城市地下管网作为城市的主要动脉线,因其敷设的隐蔽性导致对其运行状态的调查增加了难度,地下管网的设计缺陷、老化、破坏、无序建设、养护滞后等问题是管网事故及由其引发的次生灾害频繁发生的主要原因。根据城市地下管网运行现状,对地下管网隐患调查进行分类,包括设计缺陷、结构缺陷、外力破坏、生命周期和养护滞后隐患。结合地下管网普查和管道检测数据对地下管网隐患进行统计分析,为城市规划管理提供决策支持。
As the main arterial line of the city,the hidden nature of the urban underground pipe network makes it more difficult to investigate its operation status.The design defects,aging,destruction,disordered construction and lagging maintenance of the underground pipe network are the main reasons for the frequent occurrence of pipe network accidents and secondary disasters caused by them.According to the current situation of urban underground pipe network operation,the hidden dangers of underground pipe network investigation are classified,including design defects,structural defects,external force damage,life cycle and maintenance lag hidden dangers.Combined with underground pipe network survey and pipeline inspection data,the hidden dangers of underground pipe network are statistically analyzed to provide decision support for urban planning and management.
