Micro-Scale Modeling of Soil Freezing
Original language description
This contribution deals with modeling of mechanical manifestations within saturated soil, which are induced by freezing of the pore water. A simple 2D mechanical model of the phase transition in a portion of a pore is presented. This model is based on the Navier equations and on the continuity equation and serve mainly for a verification of the dynamics of the mechanical reaction. A basic qualitative computational study of this model is presented. Further, this model is generalized by supplementing it with a heat balance law onto the thermo-mechanical model describing the mutual interaction of all pore components. Thus, the extended model enables more realistic description of the studied dynamics in a more general part of the soil pore material. For this model, some basic qualitative studies, which indicate non-trivial progress of the mechanical interaction, are presented as well.
