摘要
针对雁门关隧道特长、富水软弱围岩等复杂地质条件以及工期要求紧的实际情况,采用地层—结构模式,对地层比较差的Ⅵ级围岩的稳定性进行了模拟分析,建立了隧道围岩理论模型,并对施工过程进行了数值模拟,验证了雁门关隧道快速施工的可行性,为后续工程提供一定的参考。
According to the engineering characteristics of Yanmenguan tunnel as： super long,soft surrounding rock with high water content and other geological conditions and requirements on limit time,utilizing stratum-structure mode model analysis is carried out to analysis the stability of Ⅵ surrounding rock;at the same time corresponding theoretical model is built.Numerical simulation is made for construction process,which verified the feasibility of rapid construction of tunnel and provided references for subsequent works.
