Abstract: Examples of the records of variations with time in the signal from an infrared radiometer caused by the stress variations in the ground specimen and synchronous readings of strain gauges used to calculate stress variations are given. An algorithm of processing these records is constructed. A satisfactory coincidence of the stress variations in time determined with the use of synchronous radiation and tensometric measurement data is shown. The results show the efficiency of the infrared diagnostics of periodic changes in the stress state of grounds.
