Formation of ice lenses and frost heave
[1] I examine the morphology of ice growth in porous media. Intermolecular forces cause premelted fluid to migrate and supply segregated ice growth (e.g., lenses) and frost heave. I account for the net effect of these microscopic interactions in a homogenized model formulated in terms of fundamental physical properties and characteristics of the porous medium that can be measured; no ad hoc par...
متن کاملFrost heave
The deformation of the ground surface that is produced by frost heave has motivated almost a century of concerted laboratory, field and theoretical studies. Well before the development of equipment capable of resolving the microscopic films that support liquid transport towards growing ice lenses, early investigators predicted their occurrence and noted their importance. Idealized experiments c...
متن کاملThe physics of frost heave and ice-lens growth
8 The formation of rhythmic lenses of ice in freezing soils is an intriguing geo9 physical phenomenon that is not fully understood, despite much experimental and 10 theoretical work over the past century. We review proposed mathematical models 11 of ice lens growth and frost heave, from early capillary theories and models based 12 on the concept of a frozen fringe, to more recent advances that ...
متن کاملFrost Heave in Colloidal Soils
We develop a mathematical model of frost heave in colloidal soils. The theory accounts for heave and consolidation, while not requiring a frozen fringe assumption. Two solidification regimes occur: a compaction regime in which the soil consolidates to accommodate the ice lenses, and a heave regime during which liquid is sucked into the consolidated soil from an external reservoir, and the added...
متن کاملA mathematical model of differential frost heave
The O’Neill-Miller model of frost heave, which takes account of a partially frozen fringe between the frozen and unfrozen soil, is used to study the mechanism of differential frost heave, which is a possible cause of earth hummocks and stone circles. In order to facilitate this study, the model must firstly be generalised to three dimensions, which requires a modification, due to Gilpin, of Mil...
