Review of the acoustoelaticity in rocks
岩石声弹性理论与应用的研究进展

The extensive experiments have verified the existence of the acoustoelasticity in rocks, i.e., the stress-induced wave-velocity change in rocks, which provides the possibility of the non-destructive evaluation of in-situ stress in rocks. At present, the mesoscopic and macroscopic theories for the acoustoelasticity in rocks have been presented and applied to the in-situ crustal stress measurement. In order to advance the wide application of the acoustoelasticity in rocks, this paper reviews the microscopic and macroscopic theory for the acoustoelasticity in rocks, and their application to the measurement of in-situ crustal stresses.
