摘　　要：道路的安全畅通是城市赖以生存发展的重要基础,为了避免出现桥梁安全事故,进而对社会造成巨大的负面影响,必须对管养桥梁采取监测养护措施,确保其运营安全、有序、稳定。依托于某高架立交桥预防性养护项目,以新型分布式光纤传感测器采集两次全天梁体数据,对比分析预判病害发生的部位和成因,并提出预防性意见和措施。通过智能化技术在城市桥梁预防性养护中的应用,对提升桥梁管养单位的管理水平和保障能力、确保城市桥梁群的运营安全和长久耐用有着重要的意义。Road safety and unblocked is an important basis for the survival and development of cities. In order to avoid bridge safety accidents,which will have a huge negative impact on society,monitoring and maintenance measures must be taken to manage and maintain bridges to ensure their safe,orderly and stable operation. Based on the preventive maintenance project of a viaduct,this paper collects two all-sky beam data with a new distributed optical fiber sensor,compares and analyses the location and causes of the disease,and puts forward preventive opinions and measures. Through the application of intelligent technology in preventive maintenance of urban bridges,it is of great significance to improve the management level and support capacity of bridge management and maintenance units,and to ensure the operation safety and long-term durability of urban bridges.
