摘　　要：对Tresca屈服准则、Mises屈服准则、双剪屈服准则及Mohr-Coulomb屈服准则的屈服线、屈服应力进行分析比较,找出了各种屈服准则之间的差异。探讨Mohr-Coulomb屈服准则与其他屈服准则的关系,并确定Mohr-Coulomb屈服准则在岩土工程中的安全性及岩土体破坏时的破裂面位置与滑移线之间的关系。以亚碧罗水电站实测地应力为例,对实测地应力用不同的屈服准则进行分析,论证了Mohr-Coulomb屈服准则的安全性及剪切破裂面与滑移线的差异。The yield curves and yield stress of Tresca,Mises,Double shear and Mohr-Coulomb yield criterions were discussed and compared to find the differences among them.The relation among Mohr-Coulomb yield criterion and the others were discussed,and comfirmed the safety of Mohr-Coulomb yield criterion in geo-technical engineering and the relationships between fracture plane location and slip curves when the rock and soil fractured.The different yield criterions were analyzed and compared taking Yabiluo hydropower station geo-stresses for example,and demonstrated the safety of Mohr-Coulomb yield criterion and the difference between failure surface and slip curves.
