摘　　要：确定岩石损伤张量,并对有效应力进行对称化,从而得出节理损伤岩体的本构关系。借鉴弹塑性渐进退化方法的思想,在有限元方程中实现弹塑性和损伤耦合,数值模拟圆柱体花岗岩单轴压缩实验的破坏过程,模拟的较好。The paper determines the damage tensor of a sampled rock, and symmetrizes the effective stresses, thus obtains the constitutive relationship of the cleavage damaged rock mass. With reference to the concept of the elastic--plasticity gradually generated methed, and by solving the finite element equations, a destroyed process of cylinder granite during monoaxial compressive experiment has been well simulated, and along with the coupling between the elastic---plasticity and damage.
