摘要
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 paper introduces the causes and factors influencing the buoyancy of shield tunnel.Then,it presents the buoyancy analysis model considering the transverse and longitudinal interaction,and explains the approach to determine the tunnel buoyancy and its resistant capability in single cement slurry.Taken the Shanghai Yangtze River Tunnel as an example,the paper introduces the results of buoyancy analysis and proposes the buoyancy control measures for extra-large diameter shield tunnel,providing a reference for similar projects.
