摘要
本文以我单位所施工的包西铁路后峁隧道为例,介绍了后峁隧道出洞口Ⅴ级加强围岩浅埋黄土段的施工工艺,并提出了施工建议,为以后类似地质情况下的隧道施工提供理论依据和参考。
In this paper,taking the construction of Houmao tunnel of Baotou-Xi′an railway for example,construction technology of shallow-buried loess section of V-grade reinforced surrounding rocks out of cave of Houmao tunnel was described,and construction suggestions were proposed,which provided the theoretical basis and the reference for tunnel construction with similar geological conditions.
