摘    要:对破碎体强度破坏的判别准则进行了系统分析、筛选,认为Hoek-Brown、Mohr-Coulumb、Griffith-Meclin-tock、最大张应力、最大张应变、三参数八面体剪应力、含弱面结构岩体的三维(二维)等强度准则适合于破碎体的破坏判别。应根据具体情况(岩性、岩体的破碎程度、应力状态等)选择相应的强度准则。

关 键 词:岩石破碎  岩石力学  岩石应力  破裂压力  破坏强度  破岩机理  判断  标准

Abstract:In this paper, systematic analyses are made on the failure criteria for strength failure of disintegrat-ed rock mass. It is shown that such failure criteria asHock-Brown, Mohr-Coulumb, Griffith-Meclin-tock, maximum tensile stress, maximum tensile strain, three-parametric octahedral shearing stress,two- and three- dimensional failure criterion of rock mass with weak planes, are suitable for the fail-ure determination of rock mass. The failure criteriacan be chosen correspondingly, according to the spe-cific conditions ( rock property, degree of disintegra-tion of the rock mass, and stress status, etc. ).
Keywords:Disintegrated rock mass  Rock mechanics  Failure  Mechanism  Criteria
