岩石与岩体性质的相关性研究

Study on the Correlation Between Rock Properties and Rock Mass Properties

为了解岩石性质与岩体性质的相关性,通过对阳泉矿区的岩石和岩体进行测试,研究了岩石强度与岩体强度、岩石波速与岩体波速的相关性。结果表明,岩石单轴抗压强度与岩体强度具有相似的变化趋势,并且具有显著的线性变化关系,经过拟合后的公式可以较准确地进行岩石抗压强度与岩体强度的换算。岩石的波速均大于岩体的波速,通过比例系数K表示岩体波速与岩石波速的变化关系,发现不同岩石的比例系数并不相同,并且有较大差异,岩体的波速越接近岩石的波速,说明岩体越完整。

In order to study the correlation between rock properties and rock mass properties,rock and rock mass in Yangquan coal area were tested.The correlation between rock strength and rock mass strength,as well as rock wave velocity and rock mass wave velocity is studied.The results show that the uniaxial compressive strength of rock has a similar trend to that of rock mass,and has a significant linear relationship.The fitted formula can be used to accurately convert the compressive strength of rock mass to the strength of rock mass.The wave velocity of rock is greater than that of rock mass.The relation between rock mass wave velocity and rock wave velocity is expressed by the proportional coefficient K,and it is found that the proportional coefficient of different rocks is not the same and has great difference.The closer the wave velocity of rock mass is to that of rock mass,the better the rock integrity is.
