摘要:
在单轴压缩条件下,进行白云岩破坏全过程的声发射试验研究,得到应力、声发射特性与时间的关系,并研究了岩体的Kaiser效应。结果表明:(1)岩石单轴压缩破坏过程中并不是所有试验岩样有具有典型的声发射特征阶段,部分岩样AE曲线中可以找到Kaiser效应特征点,但是多数岩样的Kaiser效应特征点不明显;(2)岩样的AE现象在应力达到峰值前会经过一个平静期,而在岩石发生破坏直至彻底破坏阶段,AE现象明显增加,这个先平静后剧增的过程可以作为预报岩爆发生的一种警示信号;(3)大多数岩样都在AE能量达到最大时发生彻底破坏。
Abstract:
Experiments on acoustic emission (AE) characteristics of complete dolomite failure process were carried out under uniaxial compression. The relations of time with AE characteristics and stresses and conclusions of Kaiser effect of the rock were obtained. Some results were shown:(1) During the loading process of compressive tests, some Kaiser effect feature point of rock samples can be found in the AE curve, but most of them are not obvious; (2) AE events remain constant before stresses become maximum, then it will increase obviously and the rock samples will be completely damaged. This process maybe a signal of rock burst; (3) Most of the rock samples are completely damaged when the AE energy of them get maximum.
