Ice segregation efficiency model of frost heave in saline soils

Arakawa's theory of frost heave is extended in order to apply it to saline soils. When the ice segregation efficiency E is a constant the model can be solved analytically. When E is not constant, solutions are obtained numerically after making several approximations applicable to short laboratory soil columns. Comparison of the model results is made with several step-freezing experiments in which the heave and water intake were measured, as well as the temperature, pore pressure and salinity profiles.
