This presentation focuses on numerical simulations of the thermal, thermo-mechanical, and thermo-hydro-mechanical response of energy piles and surrounding soils. Simulations include finite element analyses of heat transfer and coupled water flow in soils surrounding energy piles and load transfer analyses of thermo-mechanical soil-structure interaction in energy piles. Case studies involving full-scale energy piles installed in sandstone layers and centrifuge-scale energy piles installed in unsaturated silt and dry sand are presented to provide calibration data for the simulations.
