深部高应力储能岩石扰动力学行为研究现状与展望

摘要: 本文系统综述了蓄能岩石扰动力学行为研究现状与未来研究方向。首先,对深部高应力岩石扰动力学的实验装置、实验方法和理论等内容进行了梳理,并从能量角度综述了学者们对于深部岩石破坏变形的研究。然后,以深部高应力地层硬岩的岩爆、岩芯饼化等特殊力学现象为背景,从岩石微观组构的视角研究岩石蓄能机制,展示了岩石显微结构分析和岩石残余应力等相关研究的最新研究成果。在此基础上,综述了考虑岩石自蓄能的深部岩石力学响应与能量耗散机制的研究进展。最后,总结了现阶段深部蓄能岩石扰动破坏机理研究的不足,并对未来研究提出了展望。该工作可为深部高应力岩石蓄能微观机理以及自蓄能岩石能量扰动释放特性理论研究提供新的拓展思路。

 

Disturbance failure mechanism of highly stressed rock in deep excavation: Current status and prospects

Abstract: This article reviews the current status on the dynamic behavior of highly stressed rocks under disturbances. Firstly, the experimental apparatus, methods, and theories related to the disturbance dynamics of deep, high-stress rock are reviewed, followed by the introduction of scholars’ research on deep rock deformation and failure from an energy perspective. Subsequently, with a backdrop of high-stress phenomena in deep hard rock, such as rock bursts and core disking, we delve into the current state of research on rock microstructure analysis and residual stresses from the perspective of studying the energy storage mechanisms in rocks. Thereafter, the current state of research on the mechanical response and the energy dissipation of highly stressed rock formations is briefly retrospected. Finally, the insufficient aspects in the current research on the disturbance and failure mechanisms in deep, highly stressed rock formations are summarized, and prospects for future research are provided. This work provides new avenues for the research on the mechanical response and damage-fracture mechanisms of rocks under high-stress conditions.
