摘要
文章简要总结了光纤应变传感测量技术特点、应用领域及前景。对基于布里渊散射技术的分布式光纤应变测量技术（BOTDR）的工作原理、特点进行了详细阐述。以地质灾害监测实践为基础，分析了光纤应变分布和灾害体变形的对应关系。结果表明，将BOTDR技术应用于地质灾害监测中是可行的。文章还对BOTDR应用于地质灾害监测中的几个关键技术问题进行了系统总结。
In this paper, the authors briefly introduced the characteristic, application and development tendency of the technique of distributed optic fiber strain measurement, and described its principle in detail. Through our experiences on geological hazards prevention and monitoring, the distributed characteristic of optic fiber strain and relationship between deformation and strain singularity are analyzed. Our results show that BOTDR can measure the distributed displacement of the structures for geological hazards prevention. Finally, several key techniques of BOTDR are also discussed by showing our experiences of geological hazards prevention and monitoring.
