Abstract: One of the largest hydrocarbon production centers is the Yamal peninsula. The significant projected periods of operation and development of fuel and energy complex facilities at current fields indicate the relevance of issues of improving the operability of foundations in the specified climatic region, both of existing buildings and structures, and industrial facilities of new construction. This article presents the results of a review of the climatic, engineering-geological characteristics of the area, geocryological processes occurring on permafrost soils and affecting oil and gas industry facilities. The object of the study is the process of frost heaving, which has a significant seasonal effect in the form of vertical displacements of bases and foundations, including pile foundations. To improve the operability of pile foundations on permafrost heaving soils, the task was to conduct experimental studies of the operation of the traditional and proposed perforated type piles, with seasonal freezing and thawing of the soil base. According to the results of experimental and theoretical studies, a design scheme of a perforated pile was proposed, which provides a reduction in vertical movements during frost heaving up to 30 %, which is the basis for further research on pile foundation operability improvement, taking into account the obtained positive and negative operation parameters of various types of piles.
