METHOD FOR REDUCING ADFREEZE FORCE ACTING ON PILE FOUNDATIONS AT PERMAFROST

摘要

A method for reducing adfreeze bond strength acting on foundation piles at permafrost is provided to obtain excellent insulation around the foundation pile built in the permafrost by pouring a mixture of soil, plastic aggregate, and antifreeze solution. A method for reducing adfreeze bond strength acting on foundation piles at permafrost includes the steps of: mixing soil with plastic aggregate; pouring the mixture of the soil and plastic aggregate between the foundation pile and the ground; and adding antifreeze solution. The mixture contains 70~85w% of soil, 10~29w% of plastic aggregates, and 1~5w% of antifreeze solution. A diameter of the plastic aggregate is less than 5mm.
