本文在试验的基础上,研究了两类岩石材料单轴压缩下的声发射规律,发现脆性坚硬完整的材料声发射在破坏前会出现突跃;而松软材料发射平稳增加,这与其破坏现象是一致的。数值模拟表明,岩石的破坏过程与岩石的结构（均质度）存在一定的关系,模拟加载过程中的声发射规律与试验的结果一致。 Based on the experiments, the acoustic emission laws of two kinds of rock materials under uniaxial compression are studied. It is found that the acoustic emission of brittle hard and intact materials will jump suddenly before the failure, while the emission of soft materials increases steadily. Consistent. Numerical simulation shows that there is a certain relationship between the rock failure process and the rock structure (homogeneity), and the acoustic emission law during the simulation is consistent with the experimental results.
