Frost heave and heaving pressure measurements in colliery shales

open access: yesCanadian Geotechnical Journal, 1976
The 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 ...

Frost Heave in Argon

Physical Review Letters, 2000
The freezing of argon in silica powder is observed to generate bands of pure solid argon in the same manner as in the phenomenon of ice lens formation in the freezing of moist ground. A first principles dynamical theory describes the mechanism of lens formation by the thermomolecular pressure-driven flow of interfacially melted films at the lens-solid ...

The theory of frost heaving

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 in He

Physica B: Condensed Matter, 1995
Frost heave occurs in various phenomena in natural environment. It has been studied in helium on porous glasses under perfect ice-segregation condition. The maximum frost heave pressure was investigated for various conditions and was in good agreement with the thermodynamical prediction. The dynamical properties of frost heave are discussed and some of

Remarks on Frost Heave

Journal of the Physical Society of Japan, 1994
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.

Frost Heave in Soils

Journal of Applied Physics, 1966
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, 1987
The 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.
