摘　　要：在重庆交通基础设施建设过程中,如轨道交通、市政道路,由于线路纵坡限制,多采用隧道形式下穿山体。以老房子车站为例,对大断面隧道双侧壁导坑法、拱盖法两种施工工法进行工程风险、施工技术难度、投资、工期等方面的综合比选,总结出重庆大断面隧道两种开挖工法的适用条件。In the process of transportation infrastructure construction in Chongqing,such as rail transit and municipal roads,due to the limitation of longitudinal slope of the lines,tunnels are mostly used to pass through mountains.Taking the Lao Fangzi station as an example,this paper makes a comprehensive comparison of engineering risk,construction technical difficulty,investment and construction period of the two construction methods of the twin-side heading method and the arch cover method of large cross-section tunnel.Based on the analysis,the application conditions of two excavation methods of Chongqing large cross-section tunnel are summarized.

关 键 词：大断面隧道 施工工法 双侧壁导坑法 拱盖法
