Abstract

During the construction of bored piles, the heat released from cement hydration inevitably induces thermal disturbance in the surrounding permafrost, thereby altering the temperature field of the pile–soil system and influencing the refreezing process of frozen ground. Taking a bridge pile foundation project in the Chumar River region of the Qinghai–Tibet Plateau as the engineering background, a heat transfer numerical model of the pile–soil system was established using COMSOL Multiphysics. The model was employed to investigate the evolution of the temperature field under different concrete casting temperatures. The results show that the temperature evolution of the pile–soil system can be divided into three stages: heating, heat diffusion, and refreezing. An increase in the concrete casting temperature intensifies the early-stage thermal disturbance during construction and enlarges the thawing zone around the pile, while exerting only a limited influence on the long-term temperature field.
