摘要

光纤法-布（F-P）应变传感器具有稳定性好、精度高、抗电磁干扰能力强等特点

在桥梁结构状态监测中得到日益广泛的应用。介绍了F-P应变传感器的基本原理、结构及系统

并将该系统实际应用于大桥结构状态监测中。测量结果表明:光纤F-P应变传感器的测量数据能够有效地反映桥梁结构混凝土内部受温度影响的应变变化

测量系统运行正常有效。

Abstract

With the advantages of good stability

high precision and good electromagnetic resistance

the Fabry-Perot（F-P） strain sensor get increasing applications in the bridge structure status monitoring.The basic principles

combination and system of F-P strain sensor are introduced

and the system is utilized into the practical bridge status monitoring.The results show that the acquired data of F-P strain sensor can effectively describe the strain variation with the temperature change

the monitoring system works sound and effectively.
