【摘要】 在扫描电镜下，对三种类型岩石进行单轴压缩的细观力学实验，即时观察岩石变形破坏全过程．根据实验结果，可以较好的解释岩爆形成的实质．更多还原

【Abstract】 The whole process of rock de formation and failure is observed under the SEM simulta-neously when meso-mechanical experiments are being conducted with axial compression ex-erted on three kinds of rock. The experimental results have proved helpful for better explain-ing the nature of rock burst.更多还原
