| 摘 要： | 在各向异性应力状态下,岩石强度的中间主应力效应已被很多的试验所证实.基于真三轴试验结果和多轴强度准则,研究了同一中间主应力系数下岩石的多轴强度与常规三轴强度之间的关系.结果表明,在相同的中间主应力系数下,岩石的多轴与常规三轴的强度曲线具有相同的形式.对于常规三轴强度特征符合Mohr-Coulomb准则的岩石,中间主应力...

| Abstract: | In the anisotropic stress condition,the existence of the intermediate principle stress effect on the strength of rock has been verified by a large number of true triaxial tests of rock.Based on the true triaxial test data and the polyaxial strength criterions,the relationship between the polyaxial strength and conventional triaxial strength of rock at the same intermediate principle stress coefficient was studied in this paper.The results indicated that the same function of the polyaxial strength curves wit... |
