| 摘 要： | 根据岩石微结构模型及应力应变发展规律，运用统计学与损伤理论，建立了三维复合岩层的损伤演化方程及损伤本构关系。实验结果表明，二者吻合良好。这对正确描述复合岩层损伤破坏过程，深入研究层状岩体的稳定性具有实际意义。

| Abstract: | Based on microstructure model and stress strain developing of rock,the three dimensional damage constitutive and damage evolution equations of bedded composite rock are obtained by use of damage theory and statistics.The results of the experiment show that the theory curve is rather colse to the experiment curve.They are of practical significance for describing correctly damage and break process and studying the stability of bedded rockmass in a deepgoing way. |
