Freezing and Ice Growth in Frost-Susceptible Soils
Abstract A model for energy transfer, and freezing and thawing of soils is described first. This model is then incorporated into a description of heaving in frost-susceptible soils. Frost heaving is caused by formation of ice lenses, a result of transfer of unfrozen water and freezing at the cold side of the frozen fringe. The description of frost heave presented here is based on a porosity rate function. This description does not model formation of individual ice lenses; rather, it yields the average growth in porosity due to growth of ice. Application of the model is illustrated in examples of a chilled gas pipeline and a retaining wall with frost-susceptible backfill.
