Experimental on Distributed Heating Fiber Optic Sensing for Typical Seepage of Embankment
Seepage is an important factor affecting the safety of embankment engineering. It is of great significance to strengthen seepage monitoring, obtain hidden danger information in time and deal with it scientifically for ensuring the safety of the whole embankment. Guided by the heating optical fiber sensing theory, a large scale embankment model optical fiber testing platform was designed and built. With this platform, model tests of large scale embankment are carried out under three typical conditions, including variable water level, different tangential flow velocity and different rainfall patterns. The sensing efficiency of heating fiber to seepage behavior of embankment model driven by different hydraulic conditions is compared and analyzed, and the key results are summarized. The heating fiber method has little effect on expanding the monitoring range, but it can improve the sensitivity. The optical fiber in the infiltrated area has a stronger sensing ability to frequency and amplitude of fluctuations. Tangential flow velocity was positively correlated with temperature variation only in the infiltration zone. The cumulative effect of rainfall on the seepage field can be monitored.
