  4. Abstract:
  5. A 2×2 pile group with one of its piles acting as an energy pile is modeled using a 1g test setup. The model piles are closed-end aluminum pipes with 2cm diameter and 60cm length. The energy pile goes under several heating and cooling cycles which in return induces unsymmetrical loading on the pile group. A single steel U-tube through which water with a desired temperature is to be circulated is placed inside the initially water-filled energy pile to control its temperature during thermal cycling. A plastic tilt of the pile cap is observed with each thermal cycle having a gradually decreasing rate as the number of cycles increased. Readings from the horizontally oriented total pressure cells underneath the pile tips indicated changes in soil pressure during thermal cycling. Each of the heating and cooling phases had additive and subtractive effect on the soil pressure readings underneath the energy pile, respectively. Results showed that the use of unsymmetrical energy pile arrangement in a group should be approached with caution. © 2023 selection and editorial matter, Askar Zhussupbekov, Assel Sarsembayeva & Victor N.
