At the Yamburg gas-condensate deposit (GCD), tens of thousands of steel-pipe piles are sunk every year into permafrost soils by a combined drop method which consists in boring a large-diameter hole to a depth of 1-2 m, thawing the soil by a steam point to the design depth, and pressing-in the pile with the open lower end in this soil. However, a question which has not been fully elucidated in this connection is that of interaction between permafrost soils and piles sunk by this method, although their bearing capacity depends on it. When piles are sunk by the bored-drop, ordinary drop, and combined methods, the natural temperature regime of the permafrost soils is disturbed, and the times of transmission of the design load to the pile are determined by the length of the periods of its freezing-together and of attainment of the design bearing capacity of the soil base. 4 refs., 5 figs., 3 tabs.
