ABSTRACT

This paper analyzes the horizontal frost heaving force on pile foundations in slops in permafrost areas. By using the multi-physics field simulation software comsol, this paper analyzes the horizontal top displacement change patterns of the pile foundation in the slop in permafrost areas under freeze-thaw cycles. The numerical simulation results show that: the pile foundation in the slop in permafrost areas is affected by the cyclic influence of ambient temperature. Its horizontal top displacement change patterns have a shape similar to the periodic sine wave of ambient temperature. And the horizontal displacement of the pile in the downward direction along the slope is more obvious due to the horizontal frost-heaving force from the slope foundation to the pile. This paper can provide a reference for the infrastructure construction in the slope area of permafrost areas.
