摘　　要：通过对花岗岩、辉绿岩、铁矿石三种岩石进行劈裂试验和声发射试验,研究三种岩石在受拉条件下声发射信号特征差异性。研究结果表明:三种岩石都表现出较强的脆性破坏特征,在受拉破坏前声发射特征却不尽相同。The splitting test and acoustic emission test of granite,diabase and iron ore were carried out to study the difference of acoustic emission signal characteristics of the three rocks under tension.The results show that the three kinds of rocks show strong brittle failure characteristics,but their acoustic emission characteristics are different before tensile failure.
