浅埋黄土段Ⅴ级加强围岩隧道施工技术

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.
