The causes are examined for the reduction in bearing capacity and the increase in failure rate of pile foundations in permafrost soil north of the Arctic Circle. Methods of increasing or stabilizing the bearing capacity of pile supports using pile structural solutions and heat stabilizers having diverse action mechanisms.
