Abstract
Energy piles are exposed to temperature variations during their lifetime, due to their unique role combining structural support and geothermal heat exchange. Temperatures in the piles and in the surrounding soils fluctuate on a daily and seasonal basis which may cause axial displacements, additional axial stresses and changes in shaft resistance along energy piles. Furthermore, soils in the vicinity of the energy piles experience volumetric strains and changes in shear strength which may eventually have an impact on the structural behavior of energy piles. To understand the extent of temperature changes on energy piles, soils and soil-pile interfaces, various in-situ and laboratory tests have been performed. The goal of this paper is provide details regarding in-situ and laboratory tests performed on energy piles, as well as to compile an observational framework in understanding the mechanics of soils, structures and the interaction between them in consequence of thermal actions.
