Bank Slope Monitoring with Integrated Fiber Optical Sensing Technology in Three Gorges Reservoir Area
The Integrated Fiber Optical Sensing Technology (IFOST) is the integrated system for slope monitoring, including Brillouin Optical Time Domain Reflectometry/Analysis (BOTDR/A),Fiber Bragg Grating (FBG) and Raman Optical Time Domain Reflectometry (ROTDR).The specially designed sensing fibers were employed to testing the surface as well as the deep deformation of the slope, especially the shearing deformation of the slipping zone by directly embedding the sensing fibers into the soil by boreholes.As a case, the layout of the IFOST monitoring system on Block-1 of Majiagou Landslide in the Three Gorges Reservoir was introduced.The monitoring results show that IFOST is suitable for early-warming and reliable monitoring on the movement of the slope.
