| 摘 要： | 本文在弹塑性损伤的理论框架内，讨论了节理等地质间断面的本构模型。这个模型能够反映节理面的损伤弱化，扩容和弹性刚度劣化等复杂特性。这个模型的另一优点是，塑性变形增量与屈服面是非正交的，但本构矩阵具有对称性。这种对称性在岩石力学的理论研究和数值分析中是至关紧要的。

| Abstract: | The paper discusses constitutive models of geologic discontinuities(e.g.joint and fault etc.)in engineering geology within the theoretical framework of the elastoplastic damge.These models can reflect the behaviours of damage softening,elastic stiffness degradation and shear dilatancy.In the models,the plastic deformation increment is non-normal to the yield surface,but the obtained constitutive matrix is symmetrical.The former is consistent with experimental data and the latter is extremely important in the numerical analysis and theoritical research. |
