Abstract
An alternating stress as small as 5% of the static stress was found to accelerate the displacement rates of piles subjected to long-term loads in frozen soils, as well as the creep rate of frozen soil samples subjected to uniaxial loading under compression. This effect essentially reduces the bearing capacity of piles in frozen soils, and has to be taken into consideration in the design of foundations in permafrost areas.
