| 摘 要： | 自组织临界状态。是广延耗散动力学系统所普遍具有的行为特征。实验表明，岩石破裂过程也具有自组织临界特征。本文运用数学－力学分析和计算机模拟等手段。研究了岩石破裂过程中所现出的累进性破坏及无序向有序演化等特征的内在机理，从而加深了岩石破裂失稳定过程机制的认识。

| Abstract: | elf-organized criticality (SOC) is the behaviour which exists in the extended dissipative dynamical systems.Lots of experiments show that there are self-organized critical characters in the course of rock failure.In this paper, the intrinsic mechanism of progressive failure and evolutional characteristic from stochastic to regular distribution of failure which are present in the course of rock failure are studied by means of mathematical-mechanical analysis and computer simulation. It can give people a good understanding of rock failure mechanism. |
