定义了用等效剪切刚度表示的损伤变量，建立了一个分三阶段表述的岩石动态剪切损伤本构模型。

By introducing a damage variable expressed by the equivalent shear stiffness, a dynamic shearing damage constitutive model of rock is established including three phases.

在混合物理论基础上，建立了饱和、非饱和岩石损伤软化统计本构模型。

Then the statistical damage constitutive model is developed for saturated and unsaturated rock based on the mixture theory.

结合连续强度理论和统计理论，从岩石内部缺陷分布的随机性出发，建立了岩石统计损伤本构模型。

Based on random distribution of interior defect in rock, a statistical damage constitutive model for rock is developed by using the continuous strength theory and statistical theory.
