| 摘 要： | 利用广州地铁三号线某一工程实例,对连拱隧道群施工工法进行探讨。在广州地铁施工中首次提出了将连拱隧道改为单洞隧道施工技术,并对单一式中墙和分离式中墙结构的技术方案进行了比选,得出了满足结构安全、施工安全和经济效益较好的技术方案,可为今后类似工程的设计和施工提供借鉴和参考。

| Abstract: | The paper discusses the construction techniques of a group of multi-arch tunnels in a project of Guangzhou metro Line No.3.For the first time the multi-arch tunnels were driven by single borings,with a comparison carried out between the option with a single middle wall and the option with separated middle walls.Technical options were obtained that can guarantee structural and construction safety as well as economical benefits,which can be taken for reference by similar projects hereafter. |
