摘要:
在北京地铁8号线天桥—永定门外区间隧道施工过程中，盾构需要近距离地从历史保护建筑燕墩下方侧穿。借助数值分析软件对盾构侧穿燕墩的动态施工过程进行了模拟，研究并分析了盾构施工对地层变形、燕墩结构受力及变形的影响，在此基础上提出了相应的地层加固方案和盾构掘进控制措施。现场实测结果表明，采取相关防治措施后，燕墩结构及周边环境的变形得到了有效控制。
Abstracts:
During the construction of TianqiaoYongdingmen interval tunnel on Beijing metro Line 8, the shield machine needs to pass beneath the side of Yandun, a historical protection building. In order to study the stratum deformation, the structural stress and deformation of Yandun caused by the shield construction, the dynamic construction process of shield machine side passing beneath Yandun are simulated by means of numerical analysis software. On this basis, corresponding stratum reinforcement and the shield tunneling control measures are put forward. As revealed by the field monitoring results, after taking relevant prevention and treatment measures, the structural deformation of Yandun structure and the surrounding environment are effectively controlled.
