ПРОГНОЗ ТЕМПЕРАТУРНОГО РЕЖИМА НАСЫПИ СЕВЕРНОЙ ЖЕЛЕЗНОЙ ДОРОГИ (В ТУНДРОВОЙ ЗОНЕ У СТАНЦИИ ХАНОВЕЙ) ПРОГНОЗ ТЕМПЕРАТУРНОГО РЕЖИМА НАСЫПИ СЕВЕРНОЙ ЖЕЛЕЗНОЙ ДОРОГИ (В ТУНДРОВОЙ ЗОНЕ У СТАНЦИИ ХАНОВЕЙ) The article presents the results of fi eld studies near Northern Railway embankment (Hanovey station) in fi eldwork area of Geocryology Department (Lomonosov Moscow State University), where performed: cone penetration test, measuring thickness of active layer of and soil temperatures, monitoring settlement of embankment, laboratory tests. Mathematical model was compiled in the Qfrost program based on these data taking into account the unevenness of the snow cover in the study area. Calculations of the temperature regime of the embankment until 2050, carried out taking into account climatic changes (according to the RCP 4.5 scenario), showed that the thickness of the talik at the embankment will increase 40% in 30 years and without taking this factor into account — 17%. The article also discusses the features of the position and structure of the embankment, the composition and properties of frozen soils, which signifi cantly aff ect the stability of the embankment. publishedVersion
