BOTDR技术在山体滑坡监测中的应用研究
|
摘要
介绍了山体滑坡的常用监测方法,但这些方法都有其自身的优缺点,在实际应用时难以均衡各方面因素的影响。自从光纤传感技术提出以来便得到了广泛的应用,尤其是分布式光纤传感技术。基于布里渊散射的BOTDR分布式光纤传感技术,具有抗电磁干扰、长距离检测、高灵敏度等优点。由于山体滑坡体具有地形条件复杂、物质组成多样、变形部位不规则、环境因素较多等特点,本文重点探讨了将BOTDR技术应用于山体滑坡监测的方法,并提出了结合TCP/IP协议实现立体远程监测的方法。虽然BOTDR分布式光纤传感技术还有一些关键问题需要解决,但是将它应用在山体滑坡的监测中将有着显著的优势和广阔的应用前景。
In this paper,some prevalent methods of landslide monitoring are introduced,but all of them have inherent advantages and drawbacks,so it will be hard to balance the influences from various aspects.Optical sensing technology has got widely used since it is put forward,especially the distributed manner.The Brillouin optical time domain reflectometer(BOTDR) technology based on Brillouin scattering offers the potential of providing not only with immunity from electromagnetic interference,but also with long testing distance and high sensitivity.Considering the disadvantage of landslide's complex landform,multiform materials constitute and anomalistic distortion position,the method of landslide monitoring using BOTDR technology is described.A measuring system combined with the TCP/IP protocol is introduced in this paper.Though BOTDR technology has several difficulties need to be solved,it will be a better future of its application on landslide monitoring for its predominance.
