| 摘 要： | 基于岩土类介质两种常用屈服准则,摩尔库仑屈服准则和杜拉克-普拉格屈服准则相匹配关系,在引入并规定了应力罗德角的条件下推导了三轴压缩、三轴拉伸和平面应变等几种情况下岩土类介质屈服函数的等效表达公式,证明了岩土类介质屈服函数的实质是在一定应力状态下偏应力张量第二不变量与材料自身属性之间的函数关系。

| Abstract: | Based on the matching relations between two commonly used submit criterions of geo-technical material named Mohr-Coulomb and Drucker-Prager , the equivalent expression formula of submit function on geo-technical material under three axle press and stretch and so on plane strain conditions was deduced by introducing Lode influence factor, and had proven the essence of submit function on geo-technical material is under certain stress condition between the second deviator stress tensor invariant and the own attribute functional relation of materials. |
