| 摘 要： | 本文探讨了脆性破坏岩石的强度准则。根据应力空间岩石强度极限曲面的特征,选择能够反映岩石强度极限曲面特征的双剪应力和八面体剪应力两类强度准则,进行岩石强度极限曲面的回归分析,并做了红砂岩真三轴压力强度试验。根据真三轴压力强度试验资料,通过对八种岩石强度准则的回归分析对比,推荐两种三参数的双剪应力和八面体剪应力强度准则。

| Abstract: | The strength criteria of rock fragile fracture are discussed. According to the surface characteristics of rock ultimate strength in stress space, strength criteria of the twin and octahedral shear stress, which reflect the surface characteristics of rock ultimate strength, were applied to regression analysis of ultimate surface of rock strength. On the basis of data of true triaxial compression strength from experiment of red sandstone, the strength criteria of twin and octahedral shear stress with three parameters are recommended by the regression analysis for eight kinds of strength criteria. |
