- Аннотация: When the frozen kaolin is connected with the NaCl solution of 2 mol, the water and ion migrat in the direction from solution to frozen soil by the driving force of water potential gradient between frozen soil and solution under the isothermic condition. A section of frozen soil is thawed and appeared as endothermic reaction by increasing in salt concentration and by freezing point depression. The ice strip is occurred in the frozen kaolin nearby the thawing interface and appeared as exothermic reaction by water accumulation and ice segregation.Deformation is appeared in the frozen kaolin mainly in the form of frost heaving. The flux of water and ion migration and the amount of deformation is decreasing with the elapsed time in the power law and with increasing in the overburden pressure and with temperature depression.
