Abstract
Construction in the regions of the Far North is characterised by numerous natural barriers, the presence of permafrost soils in the foundations of structures, the lack of infrastructure and extreme natural and climatic conditions. Thus, the most urgent task both in design and construction, and in further operation of transport infrastructure in the Arctic regions is to ensure reliability of the foundation of the structure.
To ensure reliability of structures designed on permafrost soils, it is necessary to carry out thermophysical calculations and make forecasts of the influence of temperature processes on the foundation soils.
The territory of the permafrost soils (PFS) occupies a large part of Russia, therefore, expanding the possibilities of using these regions for development of the transportation network is an important strategic task for the state. Today, in accordance with the Strategy for Spatial Development of the Russian Federation for the period up to 2025, the Arctic zone of the Russian Federation is a priority region in terms of economic growth and strategic impact.
The article analyses the impact of the technology of seasonally operating cooling devices on the foundation soils of Salekhard- Nadym section of the Northern Latitudinal Railway line (Kilometre points 2825+00 - PK 2830+00). The effectiveness of seasonally operating cooling devices on permafrost soils of the railway embankment foundation is shown in combination with heatinsulating material. The advantages and disadvantages of seasonally operating cooling devices are summarised.
