Application of Surface Deformation Monitoring of Slope Using BOTDR Technology

LIU Yong-li,SHANG Yue-quan,YU Yang College of Civil Engineering and Architecture,Zhejiang University,Hangzhou 310027,China  
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.Based on characteristics of engineering environment,implanted fixation is used on slope volume.Introducing quasi-distributed monitoring concept,special clamps are used to fix fiber in fixed-point on front slope face.The monitoring 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.Big outer diameter is suitable for fixed-point.When temperature field changes a little,temperature compensation could be neglected.In contrary,it could be carried out by selecting similar monitoring environment and laying relaxed fiber to measure temperature changes.At the end it is discussed about fiber laying measures improvement and temperature compensation means.
