<p>The emergence of energy piles not only ensures stable bearing capacity for the overlying buildings, but also offers a novel approach to reducing building energy consumption. Through the centrifuge test, the long-term thermo-mechanical response of slender energy piles with different end restraints was evaluated under cyclic temperature. The findings indicate that after 20 thermal-cold cycles (equivalent to approximately 13&#xa0;years of prototype operation), the bearing capacities of frictional and end-bearing energy piles decreased by 15.6% and 19.5%, respectively, compared with the corresponding prototype piles. During the heating and cooling process, the change in pile side friction resistance of the friction pile is similar to that of the end-bearing pile. However, due to the limited embedding effect of the friction pile, there will still be substantial friction resistance at the end of the pile. The maximum uplift of the top of the end-bearing energy pile can reach 2.5% of the pile diameter D, which is higher than that of the frictional energy pile. Simultaneously, the ultimate bearing capacity of end-bearing energy piles is approximately 50.1% higher than that of frictional energy piles. Therefore, appropriate pile end embedding measures should be implemented to ensure that the bearing capacity of energy piles meets the requirements under cyclic temperature conditions.</p>
