| 摘 要： | 基于概率论和损伤力学对岩石在荷载作用下的破坏，损伤和弹塑性变形等特征进行了探讨，建立了弹塑性损伤统计本构模型。在损伤演化方程中全部采用有效应力，并能反映岩石剩余强度，与试验结果的比较显示了该模型的合理性。

| Abstract: | Based on the statistical and damage theory,the characteristics of elasto-plastic deformation and damage of rock are studied. The elasto-plastic statistical damage constitutive model of rock is developed. The effective stresses are totally expressed in the damage evolution function. The residual strength property of rock can be considered in the model. The presented model is verified as reasonable and practical with comparison to the experimental results. |
