Finite Element Analysis for Refrozen Process of Bored Pile in Permafrost Region
The commercially available finite element program ANSYS was used to model the refrozen process of the bored pile. The effects of the refrozen process by casting temperature of concrete, heat of concrete hydration and air convention were analyzed. To estimate the time when the bearing capacity of the bored pile is formed, the finish time of refrozen process was determined by modeling the whole refrozen process of the bored pile. The calculated results are in good agreement with experimental data. The analysis shows that the refrozen process is related with the casting temperature of concrete. The higher the casting temperature is, the more time the refrozen process takes.
