摘要
BOTDR technology is used to monitor surface deformation overcoming defects of conventional monitoring means and technology. The authors research on fixation and temperature compensation of fiber in the process of monitoring implementation, emphatically introducing laying means in the Guanjia slope of Longli freeway in Zhejiang Province. The results show that tight coated fiber of relatively small outer diameter is suitable for implanted fixation to ensure sync coordinate deformation and sensitivity of fiber is improved because of smaller sheath effects.
