摘要

岩石在循环荷载作用下产生的裂隙会降低其强度，因此研究岩石损伤演化过程具有重要意义。声发射和电阻率监测技术能够通过追踪岩石裂隙的变化来反映其损伤状态，因此可以结合这些参数来表征岩石在循环加卸载状态下的损伤过程。针对不同含水率的砂岩试样，采用声发射和电阻率监测技术对循环荷载作用过程中的岩石损伤进行监测。同时，利用计算机断层成像技术获取破裂后岩石裂隙的分布状态。基于声发射和电阻率参数，建立了损伤变量方程，并推导出单轴循环加卸载作用下的损伤本构方程。研究结果表明，以声发射和电阻率参数构建的损伤变量方程能够有效地反映砂岩在加载与卸载阶段的损伤演化过程。进一步，所提出的损伤本构方程与试验结果拟合较好，证明了该方程在研究循环荷载作用下砂岩的损伤演化规律方面具有实用价值。

Abstract

Cyclic loading induces crack formation in rock

which weakens its structural integrity. It is crucial to investigate the damage evolution process. Acoustic emission (AE) and resistivity monitoring technology can effectively track rock damage by detecting changes in fracture patterns. Integrating AE and resistivity parameters allows for a comprehensive characterization of damage progression during cyclic loading and unloading. This study employed AE and resistivity monitoring to examine damage in sandstone specimens with varying moisture contents under cyclic loading. Computed tomography (CT) scans were utilized to map crack distributions post-fracture. Using AE and resistivity parameters

damage variable equations were developed

leading to the derivation of a constitutive model for uniaxial cyclic loading and unloading. The results demonstrate that the damage variable equations accurately capture the damage evolution of sandstone during loading and unloading. The close agreement between the constitutive model’s predictions and experimental data highlights its practical utility for studying cyclic damage in sandstone.
