| 摘 要： | 大量岩石实验证明了岩石声弹现象的存在,即岩石的弹性波波速会随着岩石的应力状态的改变而改变,即岩石的声弹性现象.岩石的声弹性现象为地应力无损检测提供了可能.目前许多研究已经分别给出了岩石声弹性的细观和宏观理论,并初步应用到地应力测量方面.为了促进岩石声弹理论的应用,本文总结了岩石声弹性的细观和宏观理论研究及其在地应力测量方面应用研究的进展.

| Abstract: | 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. |
