摘要

岩石在外力作用下的破坏是外部环境与岩石系统之间的能量转换过程。本研究旨在从能量角度量化岩石破坏并预测破坏情况。利用红外辐射(IR)和声发射(AE)技术实时监测红砂岩在单轴加载实验中的破坏过程。分析了岩石破坏过程中的能量演变规律。基于斯蒂芬-玻尔兹曼定律,提出了红外指标的定量参数--平均累积辐射能量增量(ΔACRE)。得出了弹性应变能和ΔACRE之间的耦合数学模型。此外,还分析了累积 AE 能与耗散应变能之间的相关性。结果表明,根据能量演化,岩石破坏过程可分为四个阶段:压实阶段、弹性阶段、弹塑性阶段和破坏阶段。提出的 ΔACRE 可以作为划分这些阶段的依据。研究发现,ΔACRE 与弹性应变能之间存在立方多项式关系。AE 累积能和耗散应变能表现出相似的变化趋势。此外,基于ΔACRE、AE累积能和能量演化理论,提出了一种故障预测指标(IRAEER)。该指标可有效识别岩石破坏的前兆点。利用 IRAEER 作为岩石破坏变量的表征参数,创建了红外和 AE 联合作用下岩石破坏演化的定量指标,显示出较高的可靠性。这项研究为估计岩石状态和指导岩石工程结构设计提供了有力支持。

Damage quantification and failure prediction of rock: A novel approach based on energy evolution obtained from infrared radiation and acoustic emission

Rock failure under external force is a process of energy conversion between the external environment and the rock system. This study aims to quantify rock damage and predict failure from an energy perspective. Infrared radiation (IR) and acoustic emission (AE) technologies were used to monitor the failure process of red sandstone during uniaxial loading experiments in real time. The energy evolution law during the rock failure process was analyzed. Based on the Stefan–Boltzmann law, a quantitative parameter, average cumulative radiation energy increment (ΔACRE), was proposed for IR indicators. A coupling mathematical model between elastic strain energy and ΔACRE was derived. The correlation between cumulative AE energy and dissipated strain energy was also analyzed. Results reveal that the rock failure process can be divided into four stages according to energy evolution: compaction, elastic, elastic–plastic, and failure stages. The proposed ΔACRE can serve as a basis for dividing these stages. A cubic polynomial relationship was found between ΔACRE and elastic strain energy. AE cumulative energy and dissipated strain energy showed similar variation trends. Furthermore, based on ΔACRE, AE cumulative energy, and energy evolution theory, a failure prediction indicator (IRAEER) was proposed. This indicator can effectively identify precursor points of rock failure. A quantitative indicator for rock damage evolution under combined IR and AE action was created using IRAEER as the characterization parameter of the rock damage variable, demonstrating high reliability. This research provides strong support for estimating rock states and guiding the design of rock engineering structures.
