Abstract
A retrospective analysis of the results of studies of the mechanism of water migration in freezing soils was carried out on the basis of an analysis of about 160 scientific publications by Russian and 100 foreign authors. For the analysis, articles, monographs, dissertations, patents, conference proceedings and scientific reports were used. The main ones are given in the list of references. Special attention is paid to the key aspects of the formation of understanding of the driving forces of cryogenic migration (moisture transfer) in freezing soils. This analysis is necessary for the correct physical formulation of the mathematical model of the process of frost heaving of freezing soils.
