| 摘 要： | 基于数学推导,Lade-Duncan、修正的Lade-Duncan和Matsuoka-Nakai等屈服破坏准则能被转化为J2=g(θσ)?f(I1)的函数型式,并且相应这三个破坏准则的角隅函数g(θσ)被导出。尽管Lade-Duncan、修正的Lade-Duncan、Matsuoka-Nakai和Ottosen这些破坏准则具有完全不同的数学表达式,但它们都拥有共同的角隅函数和相似的内在本质联系。最后,基于混凝土和粘土的真三轴强度破坏试验结果,分别对上述破坏准则进行了系统地检测,得出了一些有益的结论。

| Abstract: | Based on mathematical calculations,failure criteria of Lade-Duncan,modified Lade-Duncan and Matsuoka-Nakai could be transformed into J 2 = g(θ σ)? f(I1),and the corresponding ridge function g(θ σ)was derived from these failure criteria.It was proved that these failure criteria shared common ridge function g(θ σ)and there were intrinsic relationships among failure criteria of Lade-Duncan,modified Lade-Duncan,Matsuoka-Nakai and Ottosen in spite of their completely different mathematical expressions.Finally,according to the true triaxial test results of concrete and clay,these failure criteria were verified and some important conclusions were obtained. |
