Аннотация: The paper is devoted to problems of the numerical simulation of the temperature regime dynamics of railway ground bases in permafrost. It provides the mathematical statement of the problem with the corresponding boundary conditions, builds up the numerical implementation based on the finite-element method, allowing the fullest accoПоказать полностьюunt for the geometry and structure of the objects of simulation. It presents the results of predicting the ground temperature state for various geometrical shapes of the embankments, including the outside conditions. The simulation of the impact of heatisolation materials and seasonal-cooling installations on the temperature regime of railway grounds has been made in the three-dimensional statement. © 2017, Pleiades Publishing, Ltd.
