| 摘 要： | 采用数值模拟分析方法,考查了不同水平距离下桩基施工对附近隧道产生的影响,旨在研究一定桩长条件下桩基与轨道交通的临界距离.研究结果表明:桩基施工对隧道竖向变形的影响较大,对水平变形的影响较小;随着水平位移的增加,隧道的水平位移、竖向位移均呈指数减小.为临近轨道交通桩基设计与施工提供参考.

| Abstract: | This paper made a study by numerical simulation on how pile foundation construction affects adjacent tunnel in different horizontal distances for the purpose of finding out the critical distance between the pile foundation and rail transit on the condition of certain pile length.The study result shows that pile foundation construction has a large influence on the vertical deformation of the tunnel but less influence on the horizontal deformation; as the horizontal distance increases,the horizontal and vertical displacements of the tunnel decrease exponentially,which may provide reference to the design and construction of pile foundation close to rail transit. |
