摘要: 在介绍国外利用盾构法技术修建地铁车站的基础上,针对我国目前修建地铁区间盾构隧道时,采用直径 6 m左右单线隧道的实际情况,提出了在区间盾构隧道的基础上扩建地铁车站的4种施工方案.根据广州地铁 3号线林和西路站的主要技术标准、修建规模以及各施工方案的特点,设计了相应的车站结构.最后,讨论了应 解决的主要技术问题,包括施工步骤、车站结构设计方法、特殊管片的设计、环境控制和工程造价.Abstract: The construction methods of overseas metro stations driven with the shield method were introduced. Based on the fact thata single-line shield tunnelhas a diameterofabout6. 0m in China, four construction schemes of ametro station driven from a sectional shield tunnelwith the expanding excavationwere proposed. According to the main technical standards and construction dimensions of Linhexilu station in the Guangzhou No. 3 metro line, the structures and construction schemes of this stationwere designed. Finally, the main related technical problems to be resolved were discussed, including construction steps, design method of station structure, design of special segmen,t environment control and project cost.
