Аnnotation: The ground penetrating radar (GPR) survey was carried out at four sites of the gas pipeline “Bovanenkovo-Ukhta” constructed in the permafrost zone. The results of these observations are presented. The informative attributes revealed from GPR cross-sections make it possible to diagnose frozen and unfrozen soil conditions and to determine the depth of seasonal thawing border for soils of different composition. Geological referencing of GPR facies distinguished was conducted using the drilling data. The features of reflections from the pipeline engineering protection systems in permafrost conditions are identified in GPR cross-sections.
