Abstract
ABSTRACT A finite-element model of a railway embankment was developed. Calculations of residual deformations of an active zone of a roadbed using the modified Mohr - Coulomb model in an elastoplastic setting, as well as a comparative evaluation of residual sediments of soil during cyclic loading from wheels of rolling stock with axle load values of 23.5; 25; 27 and 30 tf were carried out. It is shown that as the loading cycles increase, the dependence of accumulation of residual deformations for clay soils asymptotically tends to a consolidation line of II kind. The intensity of accumulation of residual deformations is higher, the greater are soil moisture and axial load. Keywords: railway embankment, soil models, finite element model, residual deformations, axial load, soil moisture. Work was made within the project RFFI 17-20-01088.
