In this study, temperature changes of the energy pile were constrained to be within a range of 5–40 °C. This range serves as an input into the thermo-mechanical analysis of the energy pile foundation, resulting in a one-way coupling between the thermal analysis of the whole system and the thermo-mechanical analysis of the energy pile foundation.
The rate of solar energy storage corresponding to the steady-state is supposed to be at the lowest level due to the gradual increase in the ground temperature. In addition, corresponding to the steady-state, there is no change in the temperature of the system, indicating that the model domain has been fully charged.
The energy pile represents an embedment of heat exchange pipes into the pile body. In this way, it can serve as a vertical heat exchanger in addition to its primary function of supporting the building. The additional land use and construction costs related to the conventional vertical boreholes of the GSHP system can thus be saved.
The results showed that the increase in the number of energy piles decreases the pile stresses but increases the displacements of the foundation to critical values. Wu et al. introduced the effect of the pile cap on the thermo-mechanical behavior of energy piles.
The heat power of the fast charging piles is recognized as a key factor for the efficient design of the thermal management system. At present, the typical high-power direct current EV charging pile available in the market is about 150 kW with a heat generation power from 60 W to 120 W ( Ye et al., 2021 ).
Wu et al. introduced the effect of the pile cap on the thermo-mechanical behavior of energy piles. They found that the pile cap poses additional restrains on the energy piles, resulting in smaller irreversible head displacements compared to that without the pile cap.
