摘　　要：盾构施工过程中常遇到管片上浮的问题,对隧道的施工质量和安全构成威胁。文章以京唐铁路北京段站前工程JTZQ-8标段项目、建宁西路过江通道A1标项目和温州越江隧道项目为例,分析盾构施工过程中常遇到的管片上浮问题,并结合管片上浮的行为机制,制订有效的控制措施,旨在为类似施工提供参考。The problem of segment floating is often encountered in the process of shield construction,which poses a threat to the construction quality and safety of the tunnel.Taking Beijing-Tangshan Railway Beijing section pre-construction engineering JTZQ-8 bid section project,Jianning West Road river-crossing channel A1 bid project and Wenzhou river-crossing tunnel project as examples,this paper analyzes the segment floating problems often encountered in the shield construction process.Combined with the behavior mechanism of segment fl oating,effective control measures are formulated to provide reference for similar construction.
