| 中文摘要: |
| 在含主应力轴旋转的土体本构关系研究的基础上，通过含主应力轴旋转的土体平面应变问题的弹塑性数值模拟结果分析，总结主应力轴旋转对土体应力分布与应形影响的规律，得出需要考虑主应力轴旋转的条件及影响的相对大小。 |
| 英文摘要: |
| Based on the former study of soils constitutive relation involving principal stress axes rotation,the influences of principal stress axes rotation on the distribution of stress and deformation of soils are provided through numerical simulation of plane strain problems of soils involving rotation of principal stress axes. The situation that rotation of principal stress axes should be considered, meanwhile the degree of its influences are presented also. |
