摘要
本文分析了加载系统的刚度对岩石断裂韧性的影响，探讨了岩石断裂韧度的依时性，并对岩石断裂中的非奇应力效应进行了分析．
In this paper, first the effect of rigidity of loading system on fracture toughness of rock is analyzed. Then the temporal coherence of fracture toughness of rock is discussed. Finally the nonsingular stress effect in rock fracture is researched.
