| 摘 要： | 讨论了线性Mohr-Coulomb屈服准则和Drucker-Prager屈服准则及其在工程计算中的应用。给出了线性Mohr-Coulomb准则在材料力学及岩石力学中的不同表达形式之间的关系;描述了线性Mohr-Coulomb准则屈服面和Drucker-Prager准则屈服面的几何性质;比较了Drucker-Prager准则采用三种不同近似方法逼近线性Mohr-Coulomb准则时的差别;最后给出了采用Drucker-Prager准则逼近线性Mohr-Coulomb准则计算桥桩基础工程实例,为了对比,同时也用Mises准则作了计算。

| Abstract: | This paper addresses the linear Mohr-Coulomb yield criterion and Drucker-Prager yield criterion, and the relation among the linear Mohr-Coulomb criteria in material mechanics and rock mechanics. The geometrical characteristics of the linear Mohr-Coulomb yield surface and the Drucker-Prager yield surface are described. The linear Mohr-Coulomb criterion is approximated using the Drucker-Prager criterion in three ways and the resultant differences are highlighted. An example is given in which the Drucker-Prager criterion is used to fit the linear Mohr-Coulomb criterion. |
