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.
