摘要
在对岩石脆性进行分析的基础上 ,提出了利用岩石的单抗拉和抗压强度 ,峰值前、后应变值来计算岩石的脆性系数 ,认为该系数是衡量岩爆倾向性的一种尺度 。
According to analysis of rock brittleness, the authors present that rock brittleness indexes are calculated by using the strength of uniaxial stretching and the strain before and behind peak of rocks. It is concluded that the indexes can be used as the yardstick of rockburst proneness, thus establishing the rockburst criterion according to the rock brittleness.
