城市下穿隧道暗埋段施工技术研究

Study on Construction Technology of Buried Section of Urban Underpass Tunnel

随着城市经济的高速发展,道路交通随之大规模发展,现有道路交通环境已无法满足城市发展的需求,辅以下穿隧道用来缓解交叉路口交通拥堵压力的设计方案比比皆是。以登封市少林大道下穿中岳庙隧道为例,论述了明挖法施工下穿隧道的分层分块原则、施工关键技术、质量控制要点等,所取得的经验可为同类工程的建设提供参考。

The city's road traffic flow grows significantly along with the development of economy,making it impossible for the current road traffic environment to keep up with the city's fast urbanization.There are numerous underpass tunnel design plan examples that reduce the burden of traffic congestion at intersections.This paper uses the Shaolin Avenue underpass tunnel through Zhongyue Temple as an example,and discusses the layering and blocking principle,key construction technologies,and quality control points of an underpass tunnel built using the open cut method,which could provide reference for similar projects.
