介绍了盾构法隧道上浮原因、影响因素、横向与纵向相互影响的上浮分析模型,以及隧道在单液浆中上浮力确定与隧道抵抗上浮能力。以上海长江隧道为例,分析了其抗浮分析结果,提出了超大直径盾构法隧道上浮控制措施,为类似工程设计提供借鉴。 The floating analysis model of the cause, influence factor, horizontal and vertical interaction of shield tunneling is introduced, as well as the determination of the buoyancy of the tunnel in single liquid slurry and the floating resistance of the tunnel. Taking Shanghai Changjiang River Tunnel as an example, the antifloating analysis results were analyzed, and the control measures of tunneling with super large diameter shield method were put forward to provide reference for similar engineering design.
