Abstract: As a new geothermal energy utilization technology, the energy pile technology has a broad development prospect because
of its high efficiency and energy saving characteristics. In order to investigate the temperature field distribution characteristics of
energy piles, ANSYS software was used to numerically simulate the heat extraction process of energy piles. The results show that
the temperature field of the energy pile is symmetrically distributed in the steady state, the radial temperature field is circular and
the longitudinal temperature field is elliptical; the thermal influence range varies with the depth of the pile; and the thermal
influence range is the largest in the middle of the pile and smaller near the top and bottom of the pile, and the maximum thermal
influence radius is about 2.2 m.

Key words: energy pile; temperature distribution; heat extraction; numerical simulation
