Specifics of finite element modelling of freezing and thawing deformations in soils

摘要

The paper describes principles of solving problems to calculate changes in stressed-strained conditions of soils during their freezing and thawing, necessary to predict behaviour of structures contiguous with these soils. Approaches are suggested whereby to choose mathematical soil models necessary to predict deformations of frost heave during freezing, including cases of water migration in soils and formation of frost related cracks, as well as models to figure out potential soil deformations during thawing.
