Abstract

The article presents a mathematical model of the process of freezing wet soil and evaluates the approximation of this model.In modeling the freezing process of the soil, we included and used various thermal and physical properties.It should be noted that they are the same for the thawed and frozen ground zones. That is, the material properties of solid and liquid phases were considered constant.The scheme of the heat exchange process in the soil is described by the method of catching the front (Lovli front) in the mesh node of the freezing of wet soil.The first phase is the molten phase, and the second phase is the frozen phase.The grid step in x, where the grid is built, is equal to the constant h. It was mentioned that the grid step in time is not constant.
