摘　　要：近年来我国城市地下轨道交通网络体系越来越完善,盾构隧道已经成为城市地铁工程建设的重要施工方法,穿越的地层条件也更加复杂,若盾构施工技术使用不合理,地层变形控制不到位,会威胁到地铁隧道安全。文中以某城市地铁工程为例,从盾构始发、盾构掘进、盾构接收方面分析隧道盾构技术要点,结合现场监测结果,该技术保证了地铁隧道建设质量与安全,可为后续类似工程提供指导与借鉴。In recent years,China's urban underground rail transit network system has become more and more perfect,shield tunnel has become an important construction method for urban subway engineering construction,and the stratum conditions are more complex.If the shield construction technology is not used reasonably,the stratum deformation control is not in place,which will threaten the safety of the subway tunnel.Taking a city subway project as an example,this paper analyzes the key points of tunnel shield technology from the aspects of shield starting,shield tunneling and shield reception,and combined with the on-site monitoring results,the technology ensures the quality and safety of subway tunnel construction,which can provide guidance and reference for subsequent similar projects.
