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 ...

Heave and Heaving Pressures in Frozen Soils

Canadian Geotechnical Journal, 1971
Most previous studies of frost heave and associated frost heaving pressures have been concerned with the process of ice lensing and ice segregation, and the primary mechanism used to explain the related phenomena of heave and pressure is seen to be consistent with the process of formation of ice lenses.
