基于M-C准则的D-P系列准则在岩土工程中的应用研究 English Version
Studies on Drucker-Prager yield criterions based on M-C yield criterion and application in geotechnical engineering

摘要: 通过适当的变化,D-P系列屈服准则便可与能够很好地描述岩土材料的强度特性的Mohr-Coulomb准则相匹配。文中对系列D-P系列屈服准则进行了比较系统及深入的研究,指出了D-P系列屈服准则的应用条件、相互之间的关系,并给出了一种D-P系列屈服准则的相互转换的方法。最后通过平面应变条件下的地基进行了有限元分析,通过与Prandtl经典理论解的对比,得出了大量有益的结论。数值分析结果有力的验证了本文有关理论的正确性。

Abstract: The relation expression of Drucker-Prager(D-P)yield criterions matched Mohr-Coulomb(M-C)yield criterion were obtained based on the Lode angle parameter.The transformation method of different Drucker-Prager yield criterion was put forward.The Drucker-Prager yield criterions matched Mohr-Coulomb yield criterion were studied profoundly.Finally,a foundation under plane strain condition was analyzed by FEM through the Drucker-Prager yield criterions.A lot of valuable results were got by contrast to the solutions of Prandtl theory and the theory of Drucker-Prager yield criterions matched Mohr-Coulomb yield criterion was proved to be correct which could be applied to the analysis of practical geotechnical engineering.
