| Summary: | Strain and temperature measurements are very important parameters to analyze
the deformation of the soil specimen. Triaxial test is the most common and established
instrumentation testing used to determine the mechanical properties of the soil
specimen. However, limitations of electric instruments in triaxial test such as
electromagnetic interference, signal loss, less stable and low resolution can create an
error in strain measurement. Fiber Bragg Grating (FBG) sensor is introduced in
monitoring field with numerous advantages compared to conventional sensing
technology. Its outstanding advantages are small sized and lightweight, immune to
electromagnetic interference, long term stability, good corrosion resistance, very low
magnetic field interactions, and ease of installation (time, cabling, and testing). This
technology has been recognized and successfully monitored for measuring various
physical quantities such as displacement, pressure and acceleration. |
