For the progressive development of modern civilization, access to minerals is critical. The main recoverable reserves of such minerals are often located at high latitudes. For example, a significant number of the world’s hydrocarbon deposits are located above 60 degrees North latitude.
Our company, Noyabrskie Power Grids, is also located in this area, and its core business is the high-quality and uninterrupted power supply to oil and natural gas industry facilities. The company operates in a hard-to-reach area with numerous swamps and lakes, in an area with complex geotechnical and geocryological conditions. Soils located in the zone of seasonal freezing are widespread here, and there are areas of permafrost soils.
The permafrost is formed in the areas of peat, loamy, and sandy sediments with considerable moisture. Soils located in the seasonal freezing zone have frost heave properties, which are shown in the irregularity of surface elevation of the freezing soil layer, replaced with the subsidence of the latter when thawing.…
