【摘要】 应用岩石破裂过程分析程序分析了侧压对预制两个平行裂纹岩样中岩桥区裂纹的扩展、贯通和相互作用机制的影响, 并对岩样。受载状态与其特征应力和峰值强度的关系进行了探讨,模拟结论与相关的实验结果相吻合。更多还原

【Abstract】 Rock failure process analysis code( RFPA2D) is used to research the rock specimen with two parallel and offset cracks, and main object is to study different confining pressure influence on propagation, coalescence and interaction of cracks in rock bridge area. Furthermore, the relation between rock specimen’s loaded state and characteristic stress is explored .The numerical result with the related experimental conclusion.更多还原
