Description	This contribution deals with two scale approaches to the mechanical manifestation modeling of freezing saturated soils. The first approach involves a macro-scale description of the problem. The mathematical model of two-dimensional two-phase system is designed. It comprises the modified heat equation involving the phase change of the pore water and the system of the Navier equations describing deformations of the body. Both equation types are coupled with the term which is related to the phase transition and which springs from the empirical considerations. Computational studies of the model for the control of the structural conditions within the mechanical heterogenious soil medium loaded by a concrete structure are presented. The second approach represents the pore-scale description of the problem. Several basic ideas regarding the local conditions of balance and mechanisms of the causes of the soil heaving inception under the thermal gradient are summed up. The preliminary simulations of the pore-scale freezing dynamics are shown. This contribution deals with two scale approaches to the mechanical manifestation modeling of freezing saturated soils.
