【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、Ｇｒｉｆｉｔｈ－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。更多还原

【Abstract】 In this paper, systematic analyses are made on the failure criteria for strength failure of disintegrated rock mass. It is shown that such failure criteria as Hock-Brown, Mohr-Coulumb, Griffith-Meclintock, 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 failure determination of rock mass. The failure criteria can be chosen correspondingly, according to the specific conditions ( rock property, degree of disintegration of the rock mass, and stress status, etc. ).更多还原
