摘要
在高速公路的隧道施工中,不同等级的岩体其开挖、支护、辅助施工的方式也不同。分析隧道开挖施工的质量控制,论述围岩开挖和初支的原则,以及在不同围岩等级、水文及工程地质条件下的施工方法及要点,可为同类施工提供借鉴。
In the highway tunnel construction ,different levels of rock mass excavation ,support ,auxiliary construction of the way is also different . This paper analyzes the quality control of tunnel excavation construction , discusses the principle of surrounding rock excavation and initial support , and the construction method and key points in different surrounding rock grade , hydrological and engineering geological conditions ,w hich can provide reference for similar construction .
