Annotation Based on the analysis of the results of experimental-theoretical studies of cryogenic heaving of soils, the possibility of using the theory of thermoelasticity to simulate the stress-strain state of a seasonally frozen layer of finely dispersed soil is substantiated. The solution of the problem of mathematical modeling of cryogenic heaving of soil with known initial and boundary conditions is presented. The solution is based on the use of the equations of the associated theory of thermoelasticity. The change in the natural soil moisture is taken as the main physical criterion for the change in the stress-strain state. The heat transfer in the proposed model is taken into account through the linear expansion coefficient of the soil during heaving. The purpose of the study is to develop a methodology for calculating the magnitude of the forces and displacements of the soil that affect the foundations of structures for various purposes.
Key words seasonally thawed soil, cryogenic swelling, stresses, deformations, thermoelasticity
