| 摘 要： | 采用光纤Bragg光栅（FBG）传感器监测了巷道模型的掘进过程。利用FLA^3D软件对巷道模型进行了掘进过程的应力分析，根据应力分布情况在巷道模型中布设了15个三维应变FBG传感器和3个温度FBG传感器，通过四通道SM125解调仪对传感信号进行系统解调以及数据存储。该传感系统测量精度高，检测的应力变化与FLAC^3D软件模拟结果吻合性好，表明FBG传感器在土木工程的监测中有较好的应用前景。

| Abstract: | The excavation process in a laneway model is monitored using fiber Bragg grating(FBG) sensors.The stress analysis of the excavation process in the laneway model is made using FLAC3D software,where based on the stress distribution 15 three dimensional strain FBG sensors and 3 temperature FBG sensors are laid in the laneway model,and the sensing signals are systematically demodulated and the data stored by using a four-channel demodulation instrument(SM125 interrogator).The sensing system has good accuracy an... |
