| 摘 要： | 软弱地基的不均匀沉降导致隧道结构产生附加结构变形与次生内力，根据大量工程实测资料，总结了包含盾构隧道施工与长期使用阶段在内的隧道地基沉降的4种典型模式．然后基于弹性地基理论，分别推导并给出了这四种地基沉降模式下隧道结构的纵向变形及结构内力解析表达式，探讨了不同地基变形模式下隧道结构的响应规律，这为隧道的纵向设计及考虑纵向剪切传递影响的横向设计研究奠定了基础。

| Abstract: | The uneven settlement would cause additional structural deformation and internal forces to tunnel in soft ground. Four settlement forms are given according to the mass field measurements of metro tunnel in Shanghai Soft ground. Then, the additional deformation and internal forces produced by the four types of ground settlement forms are deduced based on the elastic foundation beam theory. The response law of tunnel structure under different ground settlement forms is discussed. The conclusions drawn, from the theoretical deduction can serve as the base for the tunnel longitudinal design. |
