【 摘 要 】

Although the optical fiber sensing technology has been successfully applied in the geological and geotechnical engineering field, there is a deformation discrepancy between the sensing optical fiber and the rock and soil to be measured in the actual project, which has a greater impact on the monitoring results. The influences of constraint condition with optical fiber are simulated in test, the deformation coordination between the optical fiber and soil is studied through comparative test analysis. The relationship between optical fiber and load is established, as well as the relationship between actual soiled formation and load.
