APPROACHES TO STUDYING THE EFFECT OF GAS COMPONENT ON THE MECHANICAL PROPERTIES OF FROZEN SOILS

Abstract

Studies of recent decades have shown that the gas component plays a significant role in the structure and properties of frozen soils. This is indicated by a significant influx of greenhouse gases into the atmosphere from the permafrost; gas emissions leading to accidents at boreholes; the formation of gas emissions craters, etc. These processes are determined by the mutual influence between the characteristics of the gas component and the indicators of the physical and mechanical properties of frozen soils, which have not been studied enough to date. The formation mechanisms of gas-saturated zones are considered; the influence of gas on the physical and mechanical properties of thawed and frozen soils is assessed; and the processes associated with the impact of gas on the soil massif are analyzed.
