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 biaxial compression test was carried out in Fuping marble to study the acoustic emission characteristics during the failure process. According to the theory of continuous damage mechanics, the linear relationship between acoustic emission and damage variables under two-way compression was established. The occurrence of acoustic emission mechanism.
