摘要
依托大西客专忻州隧道洞身浅埋段长距离并行天然气管线设计施工沉降控制措施研究,提出大断面黄土隧道采用"双侧壁导坑法+上半断面玻纤锚杆稳定掌子面"的支护设计方案,由于采用该方案,避免了高压天然气管线长段落拆改工作,取得了较好的工程效益。
Based on the study on the settlement control techniques for the design of long distance natural gas pipe line along Datong-Xi’an Xinzhou tunnel shallow buried section,the paper proposed “double side heading method +upper half section of the stability of tunnel face fiberglass bolt”support design scheme for the large section loess tunnel.The adoption of the scheme helps avoid the demolition work of the long distance high pressure gas pipeline,and has obtained good engi-neering effect.
