| 摘 要： | 本文首先分析含Ｉ型裂纹岩石的流变断裂特性，提出了Ⅰ型裂纹流变断裂初度的三个阈值；然后应用断裂力学和粘塑性理论。得出了具有屈服、蠕变和Ⅱ型裂纹扩展等物理力学特性的岩体隧洞的衬砌与围岩应力的解析表达式。

| Abstract: | In this paper, the creep fracture characteristic of rock with Mode- I crack is investigated; then three boundary values of creep fracture toughness are given. By the use of the theory of fracture mechanics and visco-elasto-plastic theory, the stress formulas of lining and wall rock of hydraulic tunnel are also presented. |
