摘要
以广梧高速公路某隧道为工程背景,对其洞身开挖方法和超前支护的施工进行了初步探讨,并分别阐述了洞身开挖方法及两种超前支护的施工工艺,为同类浅埋偏压隧道的洞身施工提供技术指导。
Taking a tunnel engineering on Guang-Wu highway as the engineering background, this paper initially explores the hole body excavation method and advanced support construction, and respectively expounds the hole body excavation method and construction techniques of two kinds of advanced support. Thus, it has proved technical guidance for the hole body construction of similar shallow bias tunnel.
