Methods of calculating thawing and freezing in beds of structures on nonflowing types of permafrost

Pustovoit, G. P.

Abstract The causes of and conditions for the manifestation of distortions in calculations conducted by the method of auxiliary temperatures are exposed. It is indicated that the distortions are maximum beneath the edges of structures, where the design frost depth may be on the low side by a factor of two and more. A computational method, which is free of exposed drawbacks and which indicates agreement with the results of numerical modeling is developed, proceeding from analytical solution of the problem of the motion of the phase interface in quasi-stationary approximation.
