METHOD FOR REDUCING ADFREEZE FORCE ACTING ON PILE FOUNDATIONS AT PERMAFROST

摘要

A kind of method makes frost stick bond strength and be arranged to obtain excellent insulation around foundation pile for reducing to what the foundation pile in permafrost worked, is built in permafrost by falling soil, a kind of total and antifreeze solution mixture of plastics. A kind of method makes frost stick bond strength, comprising the following steps: with total mixed soil of plastics in permafrost for reducing to what foundation pile worked; The mixture of soil and the plastic products between foundation pile and ground add up to; Add antifreeze solution. Mixture contains 70~85w% soil, 10~29w% plastic aggregates, the antifreeze solution of 1~5w%. A total diameter of plastic products is less than 5mm.
