摘要：

Using the numerical code, RFPA2D, the progressive failure process of the parallel rock samples are simulated. The numerically simulated results show that not only the stiffness, but also the strength of rock sample in parallel models plays an important role in the instability of pillars. The damages always occur and develop in the pillar with the lower strength or lower elastic modulus. In addition, due to the Kaiser effect of rock, the stress-induced damage in a rock pillar is irreversible, and only when the previous stress state in the failed rock pillar is exceeded, the further damage will continue to occur.
