The Jackson-Chalmers model of frost heave is extended with a more detailed treatment of the heat flow and water transport problems in soils. Concepts derived from a study of the interaction between particles and a solid-liquid interface are combined with the previous model and applied to the formation and growth of ice lenses.

Frost Heaving Phenomena in Helium
Japanese Journal of Applied Physics, 1987The frost heaving phenomena was studied by using a combination of 4He and porous glass. We were able to set up a perfect ice segregation condition such that the frost heave occurred at the boundary between bulk solid and supercooled liquid in the pores below the bulk freezing temperature.

Treating ideal frost heave on the phenomenological level, we introduce the transport coefficient associated with the boundary between solid and porous material filled with liquid. We regard this coefficient central for basic understanding of the kinetics of frost heave.

Foundation Design for Frost Heave
Cold Regions Engineering 2009, 2009Frost heave is the heaving of the ground surface when frost-susceptible soils, in conjunction with high water table or surface water infiltration, freeze. This paper discusses the foundation design strategy for frost-heave forces in areas with substantial frost depths. Only foundations in seasonal frost areas are discussed.

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1980
Summary The mechanism by which frost heave occurs when freezing temperatures, frost-susceptible materials and an adequate supply of water occur simultaneously is outlined. Index tests for identifying frost-susceptible materials (particularly sub-base aggregates) are discussed and emphasis is given to improvements in the Transport and Road ...

Progress in Surface Science, 1978
Abstract It has been shown that the disjoining pressure contributes to the rate of thickening of ice interlayers but that the maximum pressure which can be set up owing to the crystallization of ice is determined only by the crystallization heat and the supercooling degree, and it does not depend on the disjoining pressure.

Frost heave and heaving pressure measurements in colliery shales
Canadian Geotechnical Journal, 1976The paper describes a technique for measuring the pressure generated when heaving is restrained in a frozen soil, freezing being achieved by thermoelectric cooling. Although steps were taken to minimize side wall resistance between the specimen and the test mould significant under-estimation of the pressure was unavoidable and further work is ...

Predicting Frost Heave Using FROST Model with Centrifuge Models
Journal of Cold Regions Engineering, 1998The FROST numerical model was used to predict frost heave developing in centrifuge soil models. Uncalibrated predictions of heave using Gardner’s coefficients were selected from accompanying FROST documentation based on soil grain size. The predictions were not good. However, when the parameters were calibrated to surface heave developing in one set of

The Mechanics of Frost Heaving
The Journal of Geology, 1930The old theory that frost heaving is due to change in volume of water frozen was based on experiments with closed systems.

The problem of primary frost heave with frost penetration
Mathematical Methods in the Applied Sciences, 1995AbstractThis 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 unique classical solution for this problem.
