【摘要】 应用岩石破裂过程分析软件RFPA2D,通过对具有断续软弱结构面深部岩体中隧道的变形破坏特征、隧道周边关键部位的位移和应力变化进行了分析,对巷道在载荷作用下的声发射和位移特性进进行了探讨,着重研究了深部岩体中节理对巷道稳定性的影响。这对于进一步理解深部岩体中节理对巷道影响进而采取有效的加固措施等具有重要的理论和实践意义。更多还原

【Abstract】 Using the RFPA2D,the deformation and nonlinear gradual failure characteristics of circular roadway in deep rock mass as well as the displacement and the stress variation of the key position in the periphery of the roadway are analyzed,meanwhile,the drift characters of displacement and AE is also studied under stress.The effect on drift stability by interruption joint in deep rock mass is amphasatically studied.This study is very useful and significant both in the theoretical and the practical aspect.更多还原
