Ii. Sakharov et al., ACOUSTIC-EMISSION NONDESTRUCTIVE INSPECTION OF FREEZING AND FROZEN GROUND, Russian journal of nondestructive testing, 31(3), 1995, pp. 205-211
The distinctive features of the development of acoustic emission (AE)
during freezing and thawing of soils with different grain distribution
s and moisture contents are studied. The AE activity has been found to
depend on the level of water saturation, the type of soil, and the te
mperature gradient. It is demonstrated that the beginning of the destr
uction of the hard-frozen structure can be detected on the basis of th
e emission data and information about the degree to which the soil hea
ved.
