| 摘 要： | 八车道大跨度连拱隧道的设计和施工均有较大的难度,施工期施工工序较为复杂、各道工序的相互影响、围岩多次扰动等导致施工力学行为极为复杂。结合福州机场二期高速公路八车道连拱隧道工程实践,在施工中采用先进的测量技术对该隧道围岩变形进行现场实时监测,并根据反馈的围岩变形状况判断隧道稳定性。根据监测结果,分析了围岩变形随时间的变化规律及其变形模式,并结合开挖扰动对围岩变形发展的影响进行了分析。

| Abstract: | It is difficult to design and construct in eight-lane twin tunnel.Complicated construction process and their interaction as well as disturbance of surrounding rock lead to complicated mechanical behavior.Through the in-situ measurements of eight-lane and double-arch tunnel in Fuzhou airport phase Ⅱ expressway,the influence of construction on surrounding rock deformation is considered simultaneously,internal displacement-time character of tunnel surrounding rock has been analyzed. |
