本文从另一途径(别于文献)出发,在用数理统计方法将结构面起伏状态规范化的基础上,将结构面的剪切屈服准则考虑成更符合实际的非线性模型,并利用模型的物理意义建立物理方程,最后得到屈服准则的显式表达式,以评价岩体工程中结构面的实际抗剪能力。此外,还对剪切过程中结构面的接触及破坏状态作了详细的描述。 This article starts from another approach (other than the literature) and considers the shear yield criterion of structural planes as a more practical non-linear model based on the use of mathematical statistics methods to normalize structural surface undulations, and utilizes the physics of the model. Significance Establish physical equations, and finally obtain explicit expressions of the yield criterion to evaluate the actual shear resistance of structural planes in rock mass engineering. In addition, the contact state and damage state of the structural plane during the shearing process are described in detail.
