摘要: 岩石是典型的非均匀脆性材料,其内部富含各种缺陷,在受载破裂过程中会产生大量的声发射信号。在实验室内单轴加载条件下,应用声发射监测系统以及应力分析软件(三维岩石破裂过程分析系统,RFPA3D),研究分析了不同孔洞数目岩石试样破裂机理以及其破裂过程中的行为特征。

关键词: 孔洞岩样, 破裂特征, 声发射

Abstract: Rocks were typical inhomogeneous brittle materials with abundant various deficiencies inside and will generate plenty of acoustic emission signals during damage process under loading.On the condition of uniaxial loading in laboratory,fracture mechanism and behavior characteristic during failure process of rock sample with different number of holes were studied by apply sound emission monitoring system and stress analyzing software(the 3D failure process analytic system of rock samples,RFPA3D).

Key words: Rock samples with holes, Fracture characteristics, Sound emission
