文中介绍了利用统计规律和连续损伤力学理论建立了声发射与损伤变量之间线性关系式 ;用不同孔隙率的阜平大理岩进行了双轴压缩试验 ,模拟了双向受力状态下的岩爆 ,研究了其破坏过程中的声发射特征 ,并从岩石损伤的角度分析了岩爆的发生机制。
In this paper, the linear relationship between acoustic emission and damage variables is established by using the statistical laws and the continuous damage mechanics theory. The biaxial compression tests of Fuping marble with different porosity are carried out to simulate the rockburst , Studied the characteristics of acoustic emission during its failure and analyzed the mechanism of rockburst from the perspective of rock damage.
