โœฆ Synopsis


During the construction of the Taipei Rapid Transit System TRTS tunnels, a section of tunnel in the Panchiao Line was damaged as a result of adjacent excavation. Cracks appeared in reinforced concrete segments, the concrete slab on the invert was displaced and became detached from the segments. The event is a valuable case history for establishing criteria regulating excavations to be carried out adjacent to existing tunnels.
