发布时间：2019-05-17 15:57
【摘要】：地铁隧道采用盾构法施工时,受到各种因素的影响,盾构机及隧道衬砌环的轴线会偏离设计轴线。此偏差甚至会超出允许范围,从而引起隧道施工以及运行的安全隐患。针对此问题,总结了产生轴线偏差的各个影响因子,并提出了一种有效的纠偏方法。阐述了该纠偏技术的原理和实施方法。
[Abstract]:When the subway tunnel is constructed by the shield method, it is affected by various factors, and the axis of the shield machine and the tunnel lining ring will deviate from the design axis. This deviation may even exceed the allowable range, resulting in the construction of the tunnel and the potential safety hazards of operation. In this paper, the factors affecting the axis deviation are summarized, and an effective method of deviation correction is put forward. The principle and implementation method of the rectification technology are described.
