| 摘 要： | 本文介绍了光纤法-珀应变传感器的基本原理及优点,并用其进行了混凝土固化过程中的收缩应变监测实验,在混凝土两天的固化过程中监测到了130微应变的收缩应变.本文还对光纤法-珀应变传感器的温度稳定性能进行了理论分析及对比实验,实验结果表明,在一定条件下环境温度对光纤法-珀应变传感器的影响可忽略不计,因此可不用任何温度补偿.

| Abstract: | In this paper,fiber optic Fabry-Perot strain sensor was employed in monitoring the shrink strain of concrete during cure period.The principle and experiment was studied.About 130μ∈of shrink strain has been observed in the experiment of two day’s cure period.The thermal drift experiment of sensor has also been carried out,and the experiment results indicated that fiber optic Fabry-Perot strain sensor is relatively immunity to ambient temperature. |
