This research aims to qualitatively/quantitively assess the effect of temperature variation on the energy pile shaft resistance. The important mechanisms by which heating can change the shear strength of clay and clay-concrete interface are evaluated using experimental and numerical methods. As for experimental method, temperature-controlled triaxial tests, constant normal load (CNL) direct shear tests and small-scale pile tests were conducted. As for numerical approach, a fully coupled thermo-hydro-mechanical (THM) analysis was performed to simulate the experimental test results so that the capability of such analysis to predict thermo-mechanical behavior of energy piles is evaluated. Reconstituted (HC-77) kaolin clay, one-dimensionally consolidated …
