| 摘 要： | RR二应力不变量模型研究岩石局部化变形带角，得到的预测值与实验中测得的变形带角随平均应力增加而增加的趋势以及随着最小压应力增加而减小的趋势都一致，但是得到的预测值比实测数据略小。在RR二应力不变量模型基础上，通过增加洛德角作为第三应力不变量，选用更加复杂的屈服条件，得到的三应力不变量模型，结合岩石真三轴实验，得到的预测值和实验数据关联度更高。 |

| Abstract: | The prediction with RR＇s two invariant Model are smaller than the data, while it can catch the trend of linear increase in band angle with increasing mean stress for fixed values of the least compressive stress and a decrease with increasing values of the least compressive stress. Based on the RR＇s two invariant Model, with a Lode angle as the third invariant and the more complicated yield condition, true trixial compression test was carried out. And three-invariant model was proposed in good agreement between real data and predictions. |
| Keywords: | localization deformation band angle RR two invariant model three invariant model |
