摘要
结合隧道所处地层及水文地质情况,重点介绍了隧道超前支护方案比较,通过安全、技术、经济比较,确定了合理方案,隧道施工得到了安全保障,对类似的隧道修建技术有较大的借鉴意义。
Combining with tunnel stratum and hydrological conditions,the paper mainly introduces the preliminary tunnel support scheme comparison.Based on safety,technology and economy comparison,it finally determines rational scheme and guarantees tunnel construction security,which has great referring meaning for improving similar tunnel maintaining technology.
