| 摘 要： | 采用岩石破裂过程分析RFPA^2D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。数值模拟显示了试件的破坏过程、试件破坏所表现的声发射特征以及不同节理角对岩石破坏过程的影响。研究表明，岩石断续节理破坏过程具有几个明显的不同阶段，节理的倾角对破坏过程具有明显的影响。

| Abstract: | 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 compression and shear load with the Rock Failure Process Analysis System. The simulation shows the failure process of the specimen, the acoustic emission characteristics in failure process, and the influence of different intermittent joints angles on the rock failure process. It is found that the failure process of intermittent joints rock has several obvious different stages and the intermittent joints angle greatly influences the rock failure process. |
