摘　　要：为了进行岩爆现象的分析，对大理岩进行等围压三轴压缩和峰前、峰后卸围压试验，得到三轴压缩全过程 和峰前、峰后卸围压全过程，对此过程中的强度和变形特性进行了较为系统地研究。In order to analyze rockburst phenomenon, conventional triaxial compression tests and unloading confining pressure tests at the pre-peak and post-peak of marble are conducted. The complete compression procedures and the process of unloading confining pressure are obtained. And then, systematic studies are made on the strength and displacement of marble specimen.
