Purpose: To analyse the thawing of permafrost subgrade soils through laboratory tests aimed at determining the static and dynamic deformation modules. These studies are essential for evaluating the strength characteristics and deformation properties of the soil, thereby enhancing the reliability of design and construction of structures in permafrost conditions, thus ensuring the safety of infrastructure facilities. Method: Laboratory tests were carried out using a three-axis compression device developed by “Geotek” Scientific Industrial Enterprise. Results: The primary outcomes of the investigation are the acquisition of the deformation modulus of a pre-frozen sample under both static and dynamic loading conditions. Practical significance: The results obtained are of crucial practical significance, as they provide the opportunity to develop effective technical solutions for the construction and operation of structures in permafrost regions. The significance of these studies lies in their ability to account for the unique mechanical behaviour of thawing soils, which directly affects the strength and stability of structures.
