摘　　要：研究岩石在单向压缩和剪切条件下的声发射特性，给出了试样岩石的压应力和剪应力与声发射参数的关系曲线，据此探讨了声发射信号在岩石受力、变形、以至破坏过程中的变化规律。ccording to the acoustic emission characteristics of rock under the conditions of uniaxial compression and shearing,the curves of compressive stress and shear stress of test rock versus acoustic emission was given.Based on it,the regularity of change of acoustic emission signal in the process of applied force,deformation and failure of rock was discussed.Thereby,a basis for the stability analysis of rock mass was provided.
