A computational algorithm is constructed for solution 
of the problem of freezing of water-saturated porous media with account 
for the dependence of the temperature of the phase transition of pore 
moisture on the pressure and the concentration of a dissolved impurity. 
The mathematical model of the process considered is based on a generalized 
formulation of the well-known Stefan problem. Examples convey results 
of computation.
