Abstract
An ultrasonic sensing technique and a signal interpretation method based on a spectral element multiphase poromechanical approach overcomes critical gaps in permafrost, frozen soil, and saturated soil characterization. Ultrasonic sensing produces high-quality response signals that are sensitive to the soil properties. A transfer function denoting a ratio of induced displacement and applied force in the frequency domain, is independent of the distribution of the stress force applied by the transducer to the sample, and allows interpretation of the measured electrical signal using a theoretical transfer function relation to efficiently determine the most probable properties from response signals using an inverse spectral element multiphase poromechanical approach. This ultrasonic sensing technique enables rapid characterization of soil samples in terms of both physical and mechanical properties. The Quantitative Ultrasound (QUS) system can be used in a laboratory setup or brought on site for in-situ investigation of permafrost, frozen, and saturated soil samples.
