摘　　要：本文揭示了软弱结构面和裂隙岩体直剪破坏阶段的宏观规律与微观机理，提出测定此类岩体ｃ，φ峰值的直剪单点法的理论依据和特征点判据，从理论上和试验技术上基本解决了此类岩体ｃ，φ峰值直剪单点法的可行性问题。文中还通过单点法与多点法成果对比分析验证了单点法成果的可靠性。In this paper,the macroscopic law and microscopic mechanism for the direct shear failure ofthe weak structural plane and fissured rock are revealed. The theoretical basis and characteristic pointcriterion for the single point method of the direct shear to determine peak value of c and of this rockare proposed and are discussed.The problem of the feasibiltiy of this single point method is thus solvedtheoretically and methodologically.
