| 摘 要： | 隧道施工引起围岩应力释放的问题值得关注，目前对不同开挖方式引起隧道围岩强度及破坏的研究较少.因此，通过采用岩石三轴试验机，模拟隧道的不同开挖工况，针对不同卸荷应力路径下的岩石强度及破坏特征进行了深入研究，提出了相应的结论，可为后续理论研究提供试验参考.

| Abstract: | Engineers should pay attention to stress relief of rock because of tunnel excavation.Up to now,there have been little research on the strength and failure feature of rocks around tunnels because of different excavation methods. Aiming at this phenomenon,the authors adopted rock triaxial test apparatus to model different stress unloading paths according to excavation methods.Conclusions are drawn in detail with reference value on theory research. |

| Keywords: | tunnel excavation stress unloading path failure feature rock triaxial test |
