摘要: 某地铁区间在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。对事故的工程概况、事故发生经过及抢险措施进行了介绍,并详细分析了漏水事故后地表沉降监测数据、管片变形监测数据。盾构掘进过程中,盾构机的纠偏要缓慢进行,避免对已施工管片造成损害。Abstract: The right line tunnel is leaked and the segments are damaged due to an accident happening to TBM tunneling on running section in a city. The general situations of the project, the accident process and the emergency measures are introduced. Besides, the monitoring data of surface subsidence and segment deformation are analyzed. The correction measures should be carried out slowly to avoid damage to the completed segments.
