In the last two decades, Brillouin distributed fiber-optic
sensing has became a widely accepted, mature technology. On the other
hand, geotechnical monitoring applications of this technology are still
rare, as the fragile fiberoptic and the harsh soil environment are a
difficult combination. Additionally, due to high uncertainties in soil
behavior, deeper understanding of geomechanical principles is necessary
in order to achieve meaningful results when using these sensors.
