Application of a Thermo-hydro-mechanical Model for Freezing and Thawing

Recently, a constitutive model has been developed to describe the mechanical behaviour of frozen soil as a function of temperature, all the way to the unfrozen state, and vice versa [1]. The model has been implemented as a user-defined soil model (UDSM) in the geotechnical finite element code PLAXIS 2D and applied in practical thermo-hydro...

A practical approach to obtain the soil freezing characteristic curve and the freezing/melting point of a soil-water system

Knowing that extensive field tests and laboratory tests are time-consuming and expensive, this paper describes a practical approach to obtain crucial properties of frozen soil such as the soil freezing characteristic curve (SFCC), the freezing/melting point of a soil-water system and its hydraulic conductivity by means of limited input data....

Evaluation and application of a constitutive model for frozen and unfrozen soil

Recently, a constitutive model has been developed describing the mechanical behaviour of frozen soil as a function of temperature, all the way to the unfrozen state, and vice versa (Ghoreishian et al., 2016). The model has been implemented as a user-defined soil model in the geotechnical finite element code PLAXIS 2D and applied in practical...
