Abstract Summary
A series of numerical experiments based on the Tsinghua Science Museum project were conducted to investigate the thermal behavior of energy pile group under annual, imbalanced load and the influence of pile spacing. There is a linear relationship between the flow temperature and the total heat exchange, so the proportion of thermal load borne by energy piles in a hybrid system can be determined. The pile spacing affects the magnitude of variation in heat exchange fluid temperature by influencing the degree of heat accumulation in soil.
