摘要:
某地铁区间隧道在盾构施工过程中发生漏水事故，致使区间右线隧道被淹、管片破损。对该区间隧道的损坏情况、损坏范围进行鉴定，提出采用明挖法进行修复的方案。为防止全回转钻机切割管片时产生的较大压应力和剪应力对邻近管片产生破坏,采用有限元软件ABAQUS建立三维有限元模型，分析全回转钻机切割管片对邻近完好隧道管片安全性造成的影响,以期为今后地铁盾构隧道施工中出现类似情况时制定抢险方案提供参考。
Abstracts:
A water leakage accident happened in one metro section during tunneling, leading to the right line flooding and the segment damage. After identifying the condition and scope of the damage, a repairing scheme that adopts open-cut method is proposed. To prevent the large compressing stress and shearing stress in the neighboring segments caused by the 360° rotator when cutting the segments, a 3D finite element model is established by using the software ABQUS, which could analyze the impact of 360° rotator on the intact segments in the neighboring tunnel during tunneling, aiming to provide a reference for the making of emergency plans against similar water leakage accident in the future.
