The coupled transport of mass and heat which occurs in frost heave, is described by irreversible thermodynamics. A new coupling mechanism for the transport is proposed, which assumes that water is transported from the ground where the temperature is 0 deg C to the low temperature region through capillaries as an supercooled metastable phase. In contrast to other theories, local equilibrium is not assumed. The temperature difference causes the water to flow, which in turn results in the build-up of a pressure at the bulk ice. (Author)
