Application of Mohr-Coulomb yield criterion in geo-technical engineering
LIU Ying-1, 2, YU Li-Hong-3
1�� College of Construction Engineering��Jilin University��Changchun 130026��China; 2�� Changchun Vanke Co�� Ltd��Changchun 130031��China; 3�� HydroChina Beijing Engineering Corporation��Beijing 100024��China
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��
