摘　　要：北京奥林匹克公园中心区地下交通联系通道工程下穿区内东西向干道中一路段,受现况道路及市政管线限制,采用浅埋暗挖单跨平顶直墙结构,隧道结构净跨12.25m,开挖跨度14.95m,单跨如此大跨度暗挖平顶直墙隧道在北京地区尚属首例。本文对本浅埋暗挖超大跨平顶直墙隧道相关设计与施工技术要点进行分析总结。Due to the limitation of road and buried pipelines, the underground traffic project of this paper adopts single-span tunnel with horizontal proof and straight wall, which located the center region of Bering Olympic Park. The net span and excavated span of the tunnel are 12.25m and 14.95m respectively. This is the first time to application of the super single-span tunnel with horizontal proof and straight wall in Beijing. In this paper, the key technology points of the design and construction are introduced.
