摘要
结合贵广铁路两广隧道施工,重点阐述了三洞九步开挖法的应用、施工工艺及具体施工流程,该法较好地解决了特殊地质条件下大断面山岭隧道施工中的诸多技术难题,为类似工程施工积累了宝贵的经验。
Combined with Liangguang tunnel construction of GuiGuang railway,the utilization,construction process and detail construction procedure of the three tunnels and nine steps method were illustrated.The method better resolved many technical problems of large cross section mountain tunnel in special geological situation,which accumulated expensive experience for similar engineering construction.
