| 摘 要： | 岩石变形的非线性特征主要是岩石内存在的微裂纹或微空隙闭合和张开扩展的结果。本工作考虑这些微缺陷的影响建立损伤本构理论,将其应用于根据岩石所含孔隙度不同而提出的不同模型。理论曲线和实验曲线吻合。

| Abstract: | The nonlinearty of rock deformation results mainly from closing, opening, and propagation of microcracks or microviods inside rock. Taking the influence of microdefects into account, a new constitutive relationship of damage is developed, and applied to different models of rock with different porosities. The theoretical curves consist with the experimental ones. |
