| 摘 要： | 引入碎裂岩体组合的结构模式及其变形本构规律，建立了碎裂介质圆形峒室围岩稳定和变形性质的分析理论，同时，提出以面体形变比认识围岩岩体结构特征的新观念。模型实例分析表明：碎裂岩体结构控制着围岩变形及稳起性，而且结构面的作用远远超过岩体组成成分岩块的作用。

| Abstract: | By introducting the combined structural model and its deformational constituent rule, the analysis theory of deformation and stability for orthogonal jointed surrounding rock mass around a circle chamber is established. At the same time, a new concept about deformation ratio of structure surface to block is represented in order to recognize the structural behavior for cataclasite. The practical analysis indicates that the deformation and stability are controlled by cataclasite structure and the effect of the structure surface far exceeds the rock block one. |
