A method for assessing the stress-strain state (SSS) of a railway track in the conditions of the Far North and Siberia is proposed for consideration, which consists in the fact that, in accordance with the structure of the track, three-dimensional finite element (FE) models of the studied section of the railway track with the infrastructure adjacent to it are created, harmonic loading of FE models is carried out, the stiffness of the elements of which corresponds to the stiffness of the frozen and thawed section of the railway track with the adjacent infrastructure, the results of the harmonic responses of the loaded three-dimensional finite element models are used to determine the frequency range of the experimentally measured SSS parameters.
