【 摘 要 】

A description of a new non-stationary thermophysical model in the "hot tank-frozen ground" system is given, taking into account mass transfer of pore moisture. The results of calculated and experimental data are presented, and the position of the thawing front is shown to be in good agreement with the convective heat transfer due to moisture migration in the thawed ground.
