摘　　要：以国内首例采用"先盾构后车站"施工方法的广州地铁五号线杨箕站~五羊邨站~珠江新城站土建工程为研究对象,对施工监测数据进行了综合分析,并采用有限元法对几种施工工况进行了数值模拟分析,研究了该施工方法的关键技术,为今后类似条件下采用同类方法施工提供借鉴参考。Based on the project of Guangzhou Metro Line 5 between station Yangji and Zhujiangxincheng,which is the first project constructed by 'shield first and station second' method,this paper analyzes the data of construction monitor,carrys out numerical simulation on construction modes by finite element method,studys critical technique of 'shield first and station second'method,which is truly beneficial to guiding construction in similar projects.

关 键 词：先盾构后车站 明挖法 有限元分析 关键技术
