Forecasting Stress-Strain Behavior of a Thermally-Stabilized Base

Abstract

The paper proposes an improved procedure for projecting thermal and stress-strain behavior of the base of an oil tank erected on permafrost soil by taking into account cryogenic heaving of artificially frozen soil. It was shown that the use of just thermal calculations alone (which are conventionally performed when designing buildings in cryolitic zone) is definitely insufficient for providing safety, and that thermomechanical calculations should be performed as well.
