摘　　要：滑坡问题不仅对生产安全造成威胁,有的甚至对当地脆弱的生态环境造成极大破坏,因而边坡稳定监测具有重要意义。边坡稳定的声发射监测在现场得到一定应用,但相关的基础研究却非常薄弱。实验研究了岩石剪切破坏过程的声发射活动特征和相似材料单轴压缩过程的AE活动特征,利用相似材料模型模拟了滑坡过程并进行了声发射监测。实验研究结果可以为现场监测中传感器的布设、临界参数的确定等提供依据。Slope slipping threatens safe production even destroys the environment, so stability monitoring of slope has very important significance. Stability monitoring of slope has been applied in field, but the relevant fundamental study is very weakness. The paper studies rocks AE characteristics in the course of shear and similar materials AE characteristics in the course of uniaxial compressing, as well as AE monitoring of slope slipping overall process using similar material model. The study indicates that experimental results have guiding significance for layout of transducers in field, decision of relevant critical parameters.
