In this paper, numerical investigations have been carried out to show that the freezing expansion of soil can be solved by the heat pipe. In combination with the initial conditions and boundary conditions, and by using the finite difference method and the SIMPLE programs, numerical results are derived for the model. The predictions of the study are in good agreement with the data measured for the soil temperature distribution. According to the results of the model, some mechanisms of the freezing expansion solved by the heat pipe are analysed, and some design foundations are provided for the application of the heat pipe.
