双向压缩下岩石声发射特性损伤力学分析

The analysis of rock acoustic emission characteristic under biaxial compressing using damnification mechanics

用阜平大理岩进行了双轴压缩试验 ,研究了其破坏过程中的声发射特征 ,根据连续损伤力学理论建立了双向压缩下声发射与损伤变量之间线性关系式 ;分析了声发射的发生机制。

The experiment of biaxial compressing was done with Fuping marble and the characteristic of acoustic emission in the process of damnification was studied, the linear relation between acoustic emission and damage variation under the condition of biaxial compressing was established and the occur mechanism of acoustic emission was also analyzed.
