- Аннотация: In recent decades, the world has observed an active development of northern regions around the globe. Climate change is increasing the availability of hard-to-extract natural resources mining. Railways are one of the best options for the progress of transport infrastructure in these regions due to the low cost of cargo and passenger transportation. Embankments are the most common design solution of the roadbed in areas with permanent frozen soils. However, they significantly change the conditions of heat exchange between the atmosphere and permafrost. The slope surface of the embankment increases the warming effect due to increased snow accumulation in winter and insolation in summer. Climate change accelerates permafrost degradation processes. Based on computer simulation different methods of slope surface cooling were compared for the site of the Amur-Yakutsk Mainline on ice-rich permafrost. The following cooling technologies were considered in the article: crushed stone revetment, ventilation ducts and thermal insulation material. As a result of the study, it was determined that crushed stone was most effective in neutralizing the warming effect of the slope when the air temperature rises. The results obtained for the railway section in Central Yakutia will help to select the right parameters for cooling measures when designing the railway route and reconstructing the highway in the northeastern part of Russia. Especially in areas with near-surface underground ice and ice-rich frozen soils.
