Aiming at the aeolian soil in the West Area of Liaoning Province
the moisture transfer of the freezing process is tested; and the change law of moisture content with time and temperature are obtained. A dynamic coupling model of moisture transfer in the freezing process is established based on the theories of continuum mechanics and the thermodynamics; and the numerical simulation analysis is studied by using difference method. From microscopic viewpoint
the permutation of soil grain is studied via the scanning electron microscope
which reveals the moisture transfer characteristic of aeolian soil. The results indicate that a peak of frozen moisture content is formed in frozen peak surface
which is developed for depth change with time increased. Time and temperature decide the sufficiency of moisture transfer
and the change of temperature wane with the increment of depth. From scanning pattern
we can draw that the fresh arrange of soil grain directly reflects the state of moisture transfer.
