INFLUENCE OF LOAD POTENTIAL ON MOISTURE PERMEABILITY OF SOIL

The analytical solution is obtained for the nonlinear equation of moisture permeability in a multi-phase soil medium with regard to the load potential. The effect of the external influence on the shape of the moisture content profile in soil, on the moisture permeability rate and on the velocity of the soil wetting front is studied. It is shown that infiltration zones of moisture transfer are formal and are proved neither theoretically nor experimentally. The research findings on the moisture redistribution under pressure intensity change and the calculations of moisture permeability versus depth and time are presented in graphical form.

Keywords

Moisture permeability, load potential, discontinuous flow, structural species of moisture.
