摘要
以阿尔及利亚东西高速M3标段T2隧道施工为例,探讨了该隧道软弱围岩地段的施工技术,提出了三台阶平行流水作业法施工工艺流程,详细介绍了该隧道软弱围岩地段的施工过程,积累了软弱隧道施工经验。
Taken construction work of T2 tunnel in M3 bid section in east-west expressway engineering of Algeria as example, the construction technology of big span tunnel in soft and weak surrounding rock is discussed. Three-stage parallel flow process construction technology is presented. The construction process of this tunnel in soft and weak surrounding rock section is introduced in detail, which provide good references for tunnel work with soft and weak surrounding rock.
