Holding Strength of Piles in Ice.
Piles are used in polar regions for many of the same purposes as in temperate regions, including foundations for structures in areas of permafrost and ice. The bearing capacity of piles set in permafrost and ice depends on the holding, or tangential adfreezing, strength. Tests were conducted at the...
