The object of this study is the permafrost soils of the section of the route of the main water pipeline «Tabaga-Byuteidyakh» in rural areas of Central Yakutia, spanning approximately 28 kilometers. Permafrost soils are widely developed in the Southeastern part of Central Yakutia, and are located on the Leno-Amginsky interfluve. They lie in the upper part of the geological section and are underlying on the lane of the main water pipeline route, as well as fall into the foundations of engineering structures of industrial facilities and hydraulic engineering construction. The study is based on a complex of field engineering and geological surveys, as well as laboratory studies of the physical and mechanical properties of rocks. The article discusses the features of the composition, structure and properties of rocks in this area. It is noted that among the considered soils, there is a variety of granulometric types, cryogenic texture from massive to layered, with clay soils usually of higher ice content than sandy ones. Technogenic loads are also mentioned in the form of objects of the main water supply system, consisting of pumping stations, pipelines, reservoirs and channels, which lead to significant changes in the geocryological environment and surrounding landscapes.
