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.
