为了掌握煤样加载过程中的声发射特征及变形规律,对煤样加载过程中的应力-应变-声发射特征进行测试与分析。并以损伤变量为纽带,建立了煤样变形模型。根据声发射监测结果,对应力-应变曲线进行了反演,并与实测结果进行了对比。
In order to grasp the characteristics of acoustic emission and deformation during the loading process of coal samples, the stress-strain-acoustic emission characteristics during the loading of coal samples were tested and analyzed. With the damage variable as the link, a coal-like deformation model was established. According to the results of acoustic emission monitoring, the stress-strain curve is inverted and compared with the measured results.
