The coupled transport of mass and heat which occurs in frost heave, is described by irreversible thermodynamics. The approach is macroscopic phenomenological and thus it correlated macroscopic measurable parameters. It avoids as far as possible details about mechanism and is therefore complementary to derivations by, e.g., based on microscopic models. A new derivation is given for the coupling between the transport of liquid water and the transport of heat from 0°C to the ice lens. Assumption of local equilibrium in this region is not necessary. The temperature difference over the region causes a water flux, which in turn causes a build-up of pressure gradients.

## Abstract This paper is concerned with a mathematical model for the phenomenon of primary frost heave with frost penetration, which appears in the freezing process of wet soil. The problem is formulated in the form of a free boundary problem with two free boundaries. It is shown that there exists
A study on the heaving properties of morainal loamy soil was carried out under field conditions on two grounds. The loamy soils with broken structures were situated in the form of embankments of different density on the first ground. On the second ground the heave of the morainal loamy soil with un
