| 中文摘要: |
| 基于Mohr-Coulomb准则的等效广义Mises变换理论，推导了平面应变条件下的Mohr Coulomb准则的等效广义Mises变换公式，该公式能够充分考虑膨胀角的影响，并与Mohr-Coulomb准则精确匹配，能很好的表述岩土体强度特性，可应用于工程实际中。文中对Prandtl经典算例用本文提出的方法进行了有限元分析，结果验证了文中公式的正确性并得出一些有益的结论。 |
| 英文摘要: |
| Based on the theory of equivalent generalized Mises transformation of Mohr Coulomb yield criterion, a general expression of the equivalent generalized Mises transformation formula under plane strain condition is deduced. The formula takes the effect of dilatancy angle into account and well matches with the Morhr Coulomb yield criterion. The curves of the general expression are a serial of concentric circles on the deviator plane, and their radii are related to the dilatancy angle. The validity of the formula is verified by the FEM calculation result contrast to the solution of Prandtl theory. It is concluded that the deduced formula can be used to express the strength characteristics of geomaterial and applied to engineering practice. |
