摘要
通过考虑岩石试样中预置三裂纹之间岩桥力学性质和非均匀程度，运用东北大学开发的ＲＦＰＡ（２Ｄ）系统，研究了不同性质岩 桥中裂纹扩展相互作用模式及其贯通机制。模拟结果与相关的实验研究表现较好的一致性。
in the paper, considering of the mechanical behavior and heterogeneity of rock bridges between preexisting echelon cracks in the rock specimen, the characteristics and mechanism of propagation, interaction and coalescence of cracks in the different rock bridge are studied by using RFPA^(2D) (Rock Failure Process Analysis) code newly developed by CRISR, Northeastern University. The simulated results show a good agreement with those of corresponding experiments.
