双轴加压下双裂隙类岩石材料破坏试验与数值
|
摘要
对含有2条预制裂隙的类岩石材料试件进行了双轴压缩试验,研究了岩桥倾角以及侧向压力对双裂隙类岩石材料裂纹的扩展与贯通的影响,并应用离散元法进行数值模拟,对物理试验的结果进行了验证.
The biaxial compression experiments of rock-like materials with two flaws are carried out under different rock bridge liagament angle,and lateral pressure. It obtains the influence of various factors on crack propagation,penetration of rock like materials. The results of physical experiments are verified by discrete element method.
