摘　　要：为了保证隧道施工过程和长期运营的结构安全,针对隧道结构形式、施工方法和所处环境等工程特点,设计和实施隧道结构健康监测系统(TSHMS)是保障结构安全的主要方法之一。根据南京长江公路隧道建设条件复杂的工程特点和长期运营安全监测的需要,通过对各种传感测试技术的比较研究,采用以光纤传感测试技术为主的长效监测技术实现长期监测,研究大型盾构隧道结构健康监测系统的设计研究方法。通过总结设计研究过程的主要成果,为同类盾构隧道结构健康监测系统实施提供参考和借鉴。Design and implementation of Structural Health Monitoring System（SHMS） for the safety purpose of tunnel in construction and operation is one of the primary means according to its engineering features such as structure type,construction method,environment condition,and so on.For monitoring Nanjing Yangtze River Tunnel（NYRT）,the NYRT-SHMS was taken for example due to its complex construction condition and requisite for operational safety.The key technology related to SHMS for large-scale shield tunnel was researched and the implementation is based on longevities＇ Fiber Optic Sensing（FOS） method by comparing it with all other electronic and magnetic sensing approaches.This paper focuses on summarizing the research outputs during research and design and providing references and experiences for Structural Health Monitoring System in similar engineering.
