Heaving behaviour of soils in the step freezing mode
Results are presented over a wide range of soil textures supporting the linear relation between the logarithm of frost heave rate and the cold-side temperature--overburden pressure ratio proposed by Penner and Ueda.

| Summary: | Results are presented over a wide range of soil textures supporting the linear relation between the logarithm of frost heave rate and the cold-side temperature--overburden pressure ratio proposed by Penner and Ueda. The relation is simple to determine experimentally, permits heave predictions at various other temperature and pressure conditions for engineering purposes, and allows soil frost susceptibility comparisons to be made with the results determined by other laboratories. Des résultats sont présentés pour un large éventail de textures de sols, qui confirment la relation linéaire entre le logarithme du taux de soulèvement par le gel et le rapport entre la température au front froid et la pression des terres, proposée par Penner et Ueda. La relation est simple à déterminer expérimentalement; elle permet des prédictions de soulèvement sous ces conditions pratiques variées de température et de pression et elle autorise des comparaisons entre les mesures de susceptibilité au gel de sols obtenues par des laboratoires différents.
