Keyword:  岩石实验正应力摩擦滑动破裂声发射率;
Abstract: 应用双剪法对滇西地震实验场岩石的摩擦滑动特性进行了研究。实验的岩石有花岗岩、玄武岩、正长岩和片麻岩。实验的正应力为10—40MPa。实验表明,花岗岩、玄武岩和正长岩三种岩石,当正应力为10MPa时发生稳滑,当正应力超过10MPa时发生粘滑。稳滑与粘滑过程均出现位移强化现象。片麻岩当正应力为10MPa时发生稳滑,当正应力超过10MPa时样品未滑动而发生破裂。摩擦强度值比Byerlee定律的值稍低。与济南辉长岩相比,滇西三种岩石粘滑发生时的平均应力降较低,平均错距较小,平均重复周期较短。花岗岩粘滑前声发射率明显增加,玄武岩与正长岩粘滑前声发射率变化不明显。
