岩石非弹性应变恢复(ASR)地应力测试方法中柔度研究进展评述

REVIEW ON THE RESEARCH PROGRESS OF THE COMPLIANCE OF ROCKS IN IN-SITU STRESS MEASUREMENT METHODS OF ANELASTIC STRAIN RECOVERY (ASR)

本文通过分析国内外非弹性应变恢复(ASR)法地应力测量研究现状,并对ASR法中重要的柔度参数作了系统整理,认为该测量方法在理论上逐渐趋于成熟,在技术应用上有广阔的前景,但该地应力测量原理中,针对温度、应力环境(作用应力)对ASR岩石柔度影响的研究相对较少,还存在一些缺陷,为此提出了该地应力测试方法有待改进或补充的建议,为完善ASR法地应力测量原理指明了研究方向,对今后ASR地应力测量技术的完善和发展具有重要的意义。

In this ar t icle, through the analysis of the research progress on in-situ stress measurement of Anelastic Strain Recovery （ASR） method at domestic and abroad and the systemic review of the compliance parameters of ASR method, it is believed that ASR method is mature in theory and has broad prospect in application. In the measurement principle,however, few studies on the influence of temperature and stress environment （ s tress） on the ASR compliance of rocks have been done. To this end, the suggestions on the improvement or supplement of ASR method are proposed, which point out the direction of the improvement of the measurement principles and has great importance to the development of the ASR in-situ stress method.
