Abstract

Due to cement hydration, the change rule of bearing capacity of bored pile in the refreezing process is a main theoretical foundation for the consequent superstructure construction. In order to accurately calculate the bearing capacity of pile in refreezing anaphase and telophase, the basic differential equation of load transfer function is adopted. The hyperbolic model and bilinear model were employed in a computation program to calculate the soil movements surrounding and at the end of the pile, respectively. Then the friction force, resistance of pile axis force, and the single bearing capacity of the end of pile in the refreezing anaphase and telophase were obtained. The results were validated by test data in Kunlun permafrost regions. It is also concluded that the bearing capability of the bored piles in the Kunlun area can provide enough supports to superstructures construction during the refreezing metaphase and telophase.
