| 摘 要： | 对深部工程中不同深度的巷道围岩在高地应力作用下的蠕变破坏过程进行了数值模拟，得到了时间-蠕变、水平地应力-蠕变曲线组和时间-水平地应力-蠕变三维曲面。应用Mohr-Coulomb和Griffith破坏准则，获得了高地应力岩体的蠕变破坏规律，并计算验证了郑榕明和孙钧提出的非线性流变理论。

| Abstract: | In order to obtain the rule of creep failure of high ground stress rock, the process of creep failure of surrounding rocks is simulated under the action of high ground stress at different depths in deep engineering, then time-creep, horizontal ground stress (depth)-creep curves and time-horizontal ground stress (depth)-creep curved surface are obtained. According to the rules of Mohr-Coulomb and Griffith, the theory of nonlinear creep is proved. And a new idea is offered, which predicts the deformation of tunnel wall rocks surrounding in deep engineering The non-linear rheology theory proposed by Zheng Rongming and Sun Jun is verified through calculotions. |
