Annotation:

A complex of problems related to parametric diagnostics and control of working processes of thermomechanical soil development is considered. The relevance of research on the creation of mobile installations for thermomechanical development of frozen soils using gas turbine engines during the construction and operation of oil and gas pipelines is associated, among other things, with the significantly increased volumes of diagnostics in pits, significant labor costs for performing these works and their high cost. Based on the results of theoretical and experimental studies, the mechanism of parametric diagnostics of heat and mass transfer of a vapor-gas mixture from a coolant in a pit in frozen soils is justified. Recommendations are given on the method application for diagnosing changes in the temperature of the coolant and soil in the depth of the pit, taking into account heat and mass transfer, in the process of thermomechanical impact on the soil.
