| 摘 要： | 基于晶体的压电效应,提出岩石破裂时出现的电磁脉冲现象是由压电晶体破坏导致瞬间的电荷运动而产生的假说。应用统计操作理论、对岩石在单轴加载条件下破裂所产生的电磁脉冲时间序列进行了理论的探讨,并以岩石力学失稳理论探讨岩石破裂所产生的电磁脉冲规律,试验机刚度通过影响岩样的变形速率来改变电磁脉冲规律。

| Abstract: | Based on the piezoelectric effect,a hypothesis which electromagnetic emissions were yielded by charge movements resulted by destroying piezoelectric crystals during rock fracture was established.The time sequence of electromagnetic emissions produced by rock fracture under uniaxial compression was discussed by statistic damage theory.Meantime,some laws of electromagnetic emissions were discussed by rock unstable theory.and the main factors which affect the time sequence of electromagnetic emissions were obtained.One is the distribution of piezoelectric crystals in rock,the other is the machine stiffness. |
