Abstract

The relevance of the research is caused by the necessity to evaluate the existing engineering geological conditions in relation to the intended use of the plot Vostochno-Messoyakhskoe field of Tazovsky District, Yamalo-Nenets Autonomous Okrug for construction of the pipeline. The aim of this work is to evaluate geocryological processes and build a map of engineering-geocryological zoning of the route territory. Objects of the research are the components of the geological environment considered in the design of the development of the Vostochno-Messoyakhskoe field Methods. The map of engineering and geocryological zoning is based on the data from regional geological surveys, local engineering and geological surveys along the route. When mapping the composition, temperature of soil, physico-mechanical properties of soils, distribution of the permafrost and hydrogeological conditions, presence and degree of infestation site of geological and cryogenic processes were taken into account. Results. Insufficient knowledge, poor traffic, and a large area of territory required the use of the key site method. We selected three typical sites and established regularities of the composition, condition and properties of soils and ground water within them for further extrapolation to the entire area under study. We used a chain of six taxa for zoning: Region-area-district-subdistrict-section-site. There are 3 districts, 2 subdistrict, 8 sections and 12 sites. The paper describes the selected taxa.
