摘要
文中以广西资源(梅溪)至兴安广西高速公路大叶岭隧道加固工程为例,重点研究了并行双洞小净距公路隧道施工技术,总结了施工方案的设计要点,并从隧道超前支护、中夹岩体加固、钻爆开挖三个方面展开分析,详细梳理了该工程的施工质量控制要求与方法,以期为类似工程提供参考.
Abstract
Taking the reinforcement project of the Dayeling Tunnel on the Guangxi Expressway from Meixi to Xing'an as an example,this article focuses on the construction technology of parallel double hole small net distance highway tunnels,summarizes the design points of its construc-tion plan,and analyzes its construction technology from three aspects:tunnel advance support,intermediate rock reinforcement,and drilling and blasting excavation.The construction quality control requirements and methods of this project are detailed,in order to provide effective ref-erence for similar projects.
