| 摘 要： | 邻近已有地铁隧道的深大基坑的开挖是一项非常复杂的工程,开挖工程中如何能够安全地控制地铁隧道的变形尤其重要。对某邻近地铁区间隧道的深基坑施工进行全过程跟踪监测,及时反映不同工况下基坑围护结构变形、立柱回弹的变化特征;分析基坑施工对周边环境,特别是对邻近地铁隧道的影响,同时应用三维有限元分析手段,对地铁隧道在基坑施工过程中所产生的影响进行弹塑性分析。分析结果与工程实测数据比较吻合,表明整体有限元方法可以较好地模拟此类工程问题,从而为实际工程的设计施工提供一定的理论和计算依据。

| Abstract: | The excavation of large-scale deep foundation pit adjacent to existing metro tunnel is a very complicated engineering problem,and how to control metro tunnel deformation safely during excavation is particularly important.A monitoring program,including supporting structure deformation and pillar upheaval under different working conditions,was carried out on a deep foundation pit construction in the proximity of metro tunnels.The periphery environment effects,especially nearby metro tunnels were analyzed duri... |
