摘要
针对宜万铁路齐家湾隧道DK156+000～DK156+040超浅埋段围岩软弱、浅埋偏压及山体开裂、下陷、滑移等地质条件,采用了地表和洞内外结合的注浆加固施工方案,保证了该段隧道施工安全和掘进速度。
In light of weak surrounding rock,shallow and unsymmetrical tunnel,mountain cracking,collapse,slippage and other geological conditions in Qijiawan tunnel section DK156＋000~DK156＋040 on Yi-Wan railway,it adopts grouting reinforcement construction scheme with the combination of ground surface and internal and external hole.Thus,it guarantees the tunnel construction security and diving speed.
