| 摘 要： | 考虑结构面的空间形态及其与三维应力场的关系，分析了在侧向恒应力及约束位移两类边界条件下界面剪切的滑移方向、各向异性剪胀及弧度等力学特性，研究了约束位移时应力的增量规律，并由实验结果得到验证，这些结论对正确描述与评阶界面的力学特性，分析地下工程的稳定性（如井眼稳定、套管损坏等）具有一定的参考价值。

| Abstract: | Discontinuities have important effects on stability of underground structure.Consideration of the spatial shape of jagged discontinuity and its relation with stress field.theformula of shear direction.the anisotropic dilatancy and strength properties of discontinuityin three-dimensional stress are derived under two different boundary conditions. constantforce and restrainning displacement.The widespread stress increment under the secondcondition can be calculated.The anisotropic rules of discontinuity are confirmed byexperimental data. |
