摘要
本文根据普通三轴试验中随着围压的增加岩石的变形和破坏特性的变化,划分出低围压,中等围压及高围压的界限。通过分析国内外学者的岩石真三轴试验结果,总结出了中等围压下中间主应力对不同岩石强度的影响程度和规律,并指出了莫尔(Molr)准则的适用范围。
According to variation of deformation and fracture behaviour of rock with confining pressure under conventional triaxial compression tests, the limits of the low, intermediate and high confining pressure ranges are determined. Analyzing true triaxial test results of some researchers, this paper gives the law and degree of effect of the intermediate principle stress on strength of rock and presents the adaptable range of Molr Strength Criterion.
