| 摘 要： | 从岩石微元强度分布的随机性出发，引进正确描述岩石微元强度分布的参量，建立了三维岩石损伤演化方程和岩石损伤软化本构方程，从而阐述了岩石损伤的机理。充分反映了岩石破裂的全过程，尤其是软化特性，也真实反映了岩石强度受应力状态影响的现象。该模型已由试验得到验证，具有广泛的应用前景。

| Abstract: | Based on random distribution of micro-unit strength, the three-dimensional equations of damage evolution and damage-softening constitutive model in rocks are obtained through drawing into the parameter to describe correctly the micro-unit strength of rock.Thereby, the mechanism of rock damage is expounded. The model reflects the phenomenon,in which rock strength is affected by stress states. The model is verified by the experimentsand would have a vast range of applied prospects. |
