Coupled Thermo-Poro-Mechanical Finite Element Analysis of an Energy Foundation Centrifuge Experiment in Partially Saturated Silt

Wang, W. / Regueiro, R. A. / McCartney, J. S.

This paper presents an axisymmetric fully coupled thermo-poro-mechanical (TPM) finite element analysis (FEA) of a single energy foundation centrifuge experiment in partially saturated silt conducted at the University of Colorado, Boulder (UCB). The motivation is to explore thermomechanical effects on the foundation performance and thermally induced liquid and gas flow within the surrounding soil. The paper compares modeling outcomes and experimental observations regarding thermal strains and displacements of foundations due to heating. The coupled FE model predicts solid skeleton deformation, suction, and volumetric water contents of the soil, and analyzes the thermally induced pore water vapor flow and liquid water flow.
