The relevance of the research is related to the growth of breakdown susceptibility on the linear part of the main gas pipelines caused by the influence of natural and technogenic factors in regions of distribution of eternal frozen grounds, a cross-country terrain, etc. The main aims of the study are to describe the natural zonal and regional geological factors of engineering-geological conditions of the territory of the projected gas pipeline «Power of Siberia» on the section Chayanda-Lensk, to determine classification signs of defects of the main gas pipelines caused by engineering-geological factors and widespread in the region of works; to detect the main dangerous engineering-geological processes, characteristic for the region of works and having direct impact on the system pipeline-soil. The methods used in the study: the analysis of materials of engineering-geological researches for designing the objects of the linear infrastructure of the «Power of Siberia» main gas pipeline, executed by the Federal State Unitary Enterprise «Vostsib of AGP», JSC «Ingeokom», JSC «Promneftegazproyekt», JSC «Fundamentproyekt», JSC «NPF DIEM»; gathering and processing the materials of last years, statistical data on breakdown susceptibility of the main gas pipelines of JSC «Gazprom» on the linear part owing to dangerous geological processes, natural and other technogenic factors. The results. The authors have considered the climatic, geomorphological features of the place of design of a gas pipeline «Power of Siberia». The paper introduces the description of both engineering-geological formations of parent rocks, and the characteristic of geological and genetic complexes of quaternary deposits. The authors estimated the impact of geocryologic conditions of construction and exogenetic processes on the designed object and proposed the classification of defects of the main gas pipelines caused by dangerous geological, engineering-geological processes. The key reasons and factors of the processes having direct impact on operational reliability of the pipelines were defined according to the proposed classification.
