The article presents method of modeling the phenomenon of secondary frost heaving. The authors describe also the conditions under which the model is applicable according to the assumptions used in the process of its creating. The model is rigorously mathematically formulated. A method of solving the corresponding boundary problem is given. A computation of a numerical example was made. The graph characterizing the process of ice layers formation is given. One layer is formed under some conditions and two layers are formed under other conditions. It depends on the temperature of the pipe. In the case of given numeric example the authors recom-mend how to prevent frost heaving. The recommendation is of general nature and may be used in other cases.
