摘要:
城市管网大多深埋地下，长时间运行会发生各种病害，传统检测手段无法实时获知管道状态，进而无法对管道可能发生的危害进行预判和及时采取预防措施。分布式光纤传感技术具有结构分布式、长距离和实时监测的特点，适用于地下管道监测。南京市污水第二通道工程采用分布式光纤传感技术对试验段管道的应变和温度进行了监测，通过监测数据分析了管道变化的趋势和可能存在隐患的部位，为运维单位预判和提前制定应对方案提供直接的依据，也可为类似排水管道实时监测项目提供参考。
Abstract:
Most urban pipes are deeply buried underground, and various diseases may occur during long-term operation. Traditional detection methods can not obtain the status of the pipeline in real-time, so it is impossible to predict the possible hazards of the pipeline and take preventive measures. Distributed optical fiber sensing technology with the characteristics of distributed structure, long-distance and real-time monitoring, is suitable for underground pipeline monitoring. Combined with the second sewage pipeline project in Nanjing, the distributed optical fiber sensing technology was used to monitor the strain and temperature of the pipeline in the test section. Through the monitoring data, the trend of pipeline change and the potential hidden dangers were analyzed, which provided a direct basis for the operation and maintenance unit to predict and formulate the response plan in advance, and also could provide a reference for similar real-time monitoring projects of drainage pipeline.
