摘　　要：本文运用损伤理论和微元强度统计理论导出了声发射参数与损伤参量及应变的关系模型。依据这一模型,分析了单轴压缩时岩石破坏阶段声发射特性与压机刚度的关系。在此基础上,探讨了声发射活动规律与孕震过程及地震活动的内在本质联系。The model about the relationship among AE parameters,damage variable and strain is derived by applying the damage theory and micro-element statistical strength theory. The relation between AE characteristics during rock failure and machine stiffness is analysed under uniaxial compression with the above model. Based on the above analysis, the internal connection among AE activity law and seis-mogenic process and earthquake activity is discussed.
