摘要:
为明确深部高地应力各向异性与强动载条件下注浆加固体的力学行为及层位响应机制，采用声发射(AE)和数字图像相关技术(DIC)，开展2种取芯方向、不同加载速度下不同层位试件的单轴压缩试验，分析其强度特征、损伤演化与裂纹扩展特征。研究结果表明：注浆加固体各层位试件单轴抗压强度随加载速度上升而显著提高，且水平取芯试件整体强度高于垂直取芯；试件承载过程中声发射累计振铃计数呈现上升期-活跃期-衰减期阶段性特征，且随加载速度增加呈现阶段性加速增长；基于RA/AF值和DIC分析，以垂直取芯下层位为例，拉伸裂纹随加载速度增加由84.9%先降低至72.1%后增长至97.2%，破坏模式由拉伸破坏经拉剪复合转变为高度一致的拉伸破坏。研究结果可为深部巷道注浆加固与稳定控制提供参考。
Abstract:
In order to clarify the mechanical behavior and stratified response mechanisms of grouted reinforcement under conditions of deep,high in-situ stress anisotropy and strong dynamic loading,this study combines acoustic emission (AE) and digital image correlation (DIC) to conduct uniaxial compression tests on specimens from different strata.Two coring orientations and multiple loading rates are considered,and the strength characteristics,damage evolution,and crack propagation behavior are analyzed.The results show that,for specimens from all strata,the uniaxial compressive strength increases significantly with loading rate,and specimens cored horizontally exhibit higher overall strength than those cored vertically.During loading,the cumulative AE ringing counts display a staged pattern consisting of a rising period,an active period,and a decay period,and the staged growth accelerates as the loading rate increases.Based on RA/AF indicators and DIC observations,taking the lower-stratum specimen under vertical coring as an example,the proportion of tensile cracks decreases from 84.9% to 72.1% and then increases to 97.2% as the loading rate increases,while the failure mode shifts from tensile failure to a tensile shear mixed mode and finally to a highly consistent tensile failure.These findings provide a reference for grouting reinforcement and stability control in deep roadways.
