摘要
分岔隧道是近年来兴起的一种隧道形式,通常用来限制道路的特殊区域。分岔隧道主要由4层组成:大弓段:多弓段:轨上净小段:轨分离段。结合某高速公路二期工程,通过支护措施和现场监测分析,对该隧道的设计与施工特点进行优化研究,为该隧道的建设与施工提供借鉴。
Bifurcated tunnel is a new type of tunnel in recent years,and belongs to a special area usually used to limit roads.Bifurcated tunnel is mainly composed of four layers:large bow section,multi bow section,clear small section on rail and rail separation section.Combined with the second phase project of a freeway,the design and construction characteristics of the tunnel are optimized by support measures and field monitoring analysis to provide reference for building and construction of the tunnel.
