摘要
从满足边界条件、光滑对称性和外凸性三个方面,对目前岩土工程常用的8种角隅模型进行了论 述,系统地评估了每种角隅的适用范围.通过将岩土体屈服强度准则和角隅模型有机地相结合,进一步揭示了 岩土体的强度特性.
From the views of meeting boundary conditions, smooth symmetry and convex of yield strength surface under three-dimensional principal stress space, eight different smooth ridge models which are used ingeotecnnical engineering field are commented in detail, and corresponding advanteges and disadvantages of every smooth ridge model are discussed systematically. Based on yield strength function forms of τ 8=g(θ σ)f(m σ) which are published by literature and given true triaxial strength test data of granit, strength characteristics of rock and soil materials are further revealed by means of yield strength criteria combined with these smooth ridge models.
