摘要
采用岩石破裂过程分析RFPA2D系统 ,通过对岩石断续节理在压剪荷载作用下的声发射和位移特性进行数值分析 ,研究岩石断续节理的破坏过程。研究表明 ,岩石断续节理破坏过程具有几个不同的阶段 。
The failure process of intermittent joints rock was studied on the basis of numerical simulation of acoustic emission and displacement of intermittent joints in the conditions of compress and shear load with Rock Failure Process Analysis System.The results show that several obvious different stages exist in the failure process of intermittent joints rock,and the rock failure process is obviously influenced by intermittent joints angle.
