摘要 通过对沙湾地下隧洞工程的数学仿真模型的分析,以Ⅳ类围岩典型断面为例,计算围岩位移、围岩应力、衬砌及锚杆应力等,分析不同开挖方式对隧洞围岩稳定性的影响,探讨优选隧洞的支护及开挖方式,验证设计方案的合理性。 From the analysis of Shawan underground tunnel model, we take the cross section of Ⅳ surrounding rock as an example to calculate the displacement and stress of surrounding rock, lining and the stress of anchor bolts, then to research the influences of various excavation types of the tunnel surrounding rock's stability. Finally, we optimize the support and excavation of tunnel and prove the rationality of the design.
