Assessment of compliance of foreign geotechnical complexes for calculations of freezing-thawing of soils with Russian legal normatives

“…A 10 m thick soil massive, to which a temperature of +20 0 C is applied at the upper surface, has an initial temperature of -10 0 C. The soil has the following physical characteristics: freezing start temperature T bf =0 0 C, the thermal conductivity of thawed and frozen ground 175 kJ/(day*m* 0 C); heat capacity of thawed and frozen soil 1700 kJ/(m 3 * 0 C). Dry soil density 1 g/cm 3 , water content w tot =0.4, plasticity limit…”

“…Under the conditions of active development of the Far North regions, the issue of modeling the processes occurring in the soils while freezing and thawing becomes extremely relevant. The program "Termoground" was developed with the participation of specialists of St.-Petersburg transport university [1][2][3] as part of the FEM Models software package, which allows analyzing freezing and thawing processes, as well as frost heave and thawing deformations using the calculated temperature and water content fields. The Term-ground package has a long experience of successful use in the practice of calculations and design, the theoretical assumptions implemented in it are verified and fully meet the requirements of domestic codes.…”
