摘要
基于对滑坡地质灾害监测重要性的基础上,从光纤传感技术在监测领域的力学理论、监测原理、光纤的选择及应当注意的问题等方面重点探讨了新发展起来的Bragg光纤光栅(FBG)监测方法和布里渊光时域反射(BOTDR)技术监测方法,两种方法优点突出,具有广泛的发展前景。最后做了展望,指出光纤监测是未来地下工程监测领域的发展趋势。
Based on the importance of landslide monitoring system,the recent development Bragg the optical fiber diffraction grating （FBG） monitor method and the Brillouin light time domain reflects the （BOTDR） technology monitor method which had been emphasis discussed in this paper from the mechanics theory of the optical fiber sensing technology in the monitor domain, the monitor principle, the optical fiber choice, aspects and so on question which had to pay attention. The advantages and disadvantages of this two methods are pointed out. Which have prominent advantages and wide development prospects. At last, it has made the forecast, pointed out the optical fiber monitor will be the future underground project monitor domain trend of development.
