Abstract
The thermally stimulated acoustic emission of samples of sandy-clay soils under a mechanical load was studied experimentally. The characteristics of the acoustic emission upon freezing and thawing of soils as a function of their content of clay and sandy particles as well as the magnitude of the load were determined. It was shown that different stages of the stress-strain state of soils can be identified according to the thermally stimulated acoustic emission parameters. A numerical thermo-acousto-emission criterion for evaluating the rupture rate of structural bonds in frozen soils upon their warming and the change of the stress state was developed.
