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.关键词
