Abstract

As a result of monitoring observations, it was found that the frequency of subsidence in different sections of the railway embankment in different years is associated with different engineering and geological conditions and leading cryogenic processes. It requires the special geocryological zoning of the territory adjacent to the railway to develop an engineering protection strategy. The criteria for ranking areas with embankment settlements according to their hazard degree, which are divided according to spatial and temporal characteristics are proposed. It was revealed that the long-term climate changes lead to a regional change in geocryological conditions (primarily the temperature regime of soil). The extreme climatic events and variable technogenic loads cause activation or attenuation of cryogenic processes.
