The research studied several mathematical models for ground freezing processes. We can summarize the specific objects of the research under the following statements: (a) reviewing the extant models on ground freezing according to the classification in (1) models with a sharp interface between frozen and unfrozen region, (1) models with a frozen fringe (b) examining the possibility of describing heaving with or without ice lens formation by means of models of class (1) (c) studying models of class (1) under various degrees of approximation.
