摘要
声发射是岩石在受力变形和破裂过程中的重要物理现象,也是反映岩石力学特性的一个直接参量。通过对某矿山矽卡岩、石英闪长岩、蛇纹岩和粉砂岩单轴应力 应变全过程变形特性和全过程声发射特征研究,并作了对应分析,结果表明岩石的变形速率与岩石声发射事件出现的频率有较好的对应性。
Acoustic emission is an important physical phenomenon when rocks are deformed and fractured due to loading. It is also a direct parameter to show the mechanical property of rocks. The properties of full deformation and acoustic emission of skarn, quartz diorite, serpentinite and siltstone from a mine under the uniaxial compress load are introduced and analyzed in this paper. The results got from the analysis show that there is a better consistency between the deformation rate and acoustic emission frequency of rocks.
