| 摘 要： | 为了研究岩块中含有的双组平行节理在岩块受力过程中的开裂、扩展情况,以及扩展过程中对于岩块内应力的影响,使用DDARF模拟了含有双组平行节理的试块的单轴压缩试验,得出了双组平行节理角度为30°时试块最不容易发生破坏,节理角度为60°时试块最容易发生破坏的结论。

| Abstract: | The paper studies the rock stress joint stress crack and propagation with double-parallel joint, analyzes the impact of internal stress in propagation process, applies DDARF and simulates single axial compaction test of double-parallel joint test rock, and concludes that： when the double-parallel joint angle is 30°, the test block is uneasy for fracture, when the joint angle is 60°, the test block is easy for fracture. |

| Keywords: | DDARF double-parallel joint different angle test block fracture |
