摘要
介绍了BOTDR光纤应变监测技术的基本原理。从结构分析出发,论证了基于BOTDR的结构健康监测及诊断技术应用于隧道结构安全监测的可行性。结合实例对隧道结构健康监测及诊断系统的组成部分(光纤传感器、信息采集与处理、健康诊断、安全评估)进行了应用研究。最后列出了基于BOTDR的健康监测及诊断系统在隧道应用中取得的部分成果。
The paper introduces the fundamental principle of BOTDR fiber optic strain monitoring. Beginning with structure analysis, it demonstrates the feasibility of using structure health monitoring and diagnosis based on BOTDR into tunnel safety monitoring. With an example of a tunnel, it carries out an application study on the parts of tunnel structure health monitoring and diagnosis system： fiber optic sensor, information collecting and processing, health diagnosis and safety evaluation. In the end, it lists some progress of the system′s application on tunnel.
