Представлены результаты теоретического анализа и лабораторных исследований разнонаправленного деформационного процесса пучения промерзающих грунтов на примере широко распространенного в слое сезонного промерзания-оттаивания на территории России суглинка легкого песчанистого. Развиты представления о характерных зонах промерзающего грунта, а именно, добавлена зона криогенной контракции, обоснован механизм ее образования и показана роль в криогенном пучении грунтов. Результаты важны для физической постановки математической модели промерзания и пучения глинистых грунтов с учетом тепломассопереноса, разнонаправленных деформаций применительно к основам геокриологического прогноза устойчивости зданий и сооружений в области распространения пучинистых грунтов в холодных регионах России. The article presents the results of a theoretical analysis and laboratory studies of the zonality of the multidirectional deformation process of heaving of freezing soils using the example of light sandy loam widespread in the seasonal freezing-thawing layer in Russia. Ideas about the characteristic zones of freezing soil are developed, namely, a cryogenic contraction zone is added, the mechanism of its formation is substantiated, and the role in cryogenic heaving of soils is shown. The results are important for the physical formulation of a mathematical model of freezing and heaving of clay soils, taking into account heat and mass transfer and multidirectional deformations, in relation to the fundamentals of geocryological forecasting of the stability of buildings and structures in the area of distribution of frost-susceptible soils in the cold regions of Russia.

Abstract The article presents the results of experimental studies of the unfrozen water content (Ww) in frozen soils with different grain size distributions with a degree of peatification from 3 to 100% (in increments of 10%). The obtained patterns Ww = f(t °C) are discussed. The role of the organic matter content in the formation of the phase composition of moisture in the temperature range from 0 to –18°C is estimated. The study primarily considers the patterns of moisture changes due to unfrozen water with a degree of peatification above 50%, when soils are referred to peat according to GOST 25 100–2020. The patterns of the change in Ww from the degree of peatification at fixed temperatures are given.

As a result of increasing permafrost degradation, caused by climate warming, there is a growth in the number of deformations of buildings and structures in the regions of the Russian Arctic. The article examines in detail examples of building deformations in the north of the European part of Russia, in Western and Eastern Siberia, and on the Russian Arctic coast. The authors analyze and typify main causes of contingency situations. These include insufficient engineering and geological surveys, design errors, poor-quality construction of buildings and structures and violations of current standards for their operation. A serious risk factor in the construction and operation of civil and industrial facilities in the Arctic zone of the Russian Federation caused the liquidation of the previously existing system for monitoring the condition of capital structures, design and technical services that specialized in the restoration and repair of damaged buildings. At the same time, following up the construction practice without taking into account regional forecasts of the permafrost state under climate change can multiply the damage from global warming. To solve the problem, it is necessary to restore the system of control, notification and protection of structures, based on the creation of a federal system for permafrost monitoring, including background and geotechnical components, and uniting various departments and economic entities. This measure will significantly reduce the technical and environmental costs of current economic activity in the Russian Arctic.

Air temperature in the Northern Hemisphere has been progressively warming in the recent decades, and the ground temperatures have increased correspondingly. The air temperature increasing due to the climate change induces degradation of permafrost and frost heaving activation. The frost heaving forces cause unevenly distributed damaging displacement of foundations and thus poses problems to the development of Arctic regions. Frost-heave uplift forces can be reduced by protecting piles with an OSPTReline (or Reline) polymer heat-shrinkable jacket. The interaction of heaving soil with a pile covered with the Reline jacket is modeled in laboratory to estimate the uplift force and the related shear strength of frozen soil along the soil-pile adfreeze surface at temperatures from −6 to −1 °C. The data are obtained for silty sand and silty clay soils and mortar (1:5 cement-sand mixture). The experiments show that frost-heave uplift forces on Reline-protected piles are 52% to 85% lower than on uncovered steel piles (steel grade 09G2S—analog to European steel grade S355JR), depending on soil type and temperature.
