以博(罗)深(圳)高速公路清林径隧道为背景,探讨了三台阶法和环状导坑留核心土开挖工法在隧道施工中相互转换的应用情况,在施工中由于工法的及时转换,既能保证围岩的稳定性,又能适当的加快施工进度,对今后软弱围岩中的隧道施工具有一定的指导作用。
以博(囉)深(圳)高速公路清林徑隧道為揹景,探討瞭三檯階法和環狀導坑留覈心土開挖工法在隧道施工中相互轉換的應用情況,在施工中由于工法的及時轉換,既能保證圍巖的穩定性,又能適噹的加快施工進度,對今後軟弱圍巖中的隧道施工具有一定的指導作用。

Taking QingLinJing Tunnel of cussed application of conversion between BoLuo -ShenZhen Expressway as three- step method and the ring the background, this paper has dis- heading excavation method with core soil remaining, in the construction, due to timely conversion of the construction method, not only the stability of surrounding rock has been guaranteed, but also the construction schedule has been appropriately accelerated, which can be used as references for the soft surrounding rock tunnel construction in the future.
