Abstract
In this paper, the heaving of an airport runway in Taipei due to shield tunneling for the construction of Taipei Rapid Transit Systems (TRTS) was reported. The runway heaving incident, its emergency treatment, and the causes of this incident were introduced. It was found that, the mud injection pressure at the face, and backfill grouting pressure were significantly greater than the limiting values assumed for construction. The material ejected to the ground surface was found to be the same as the mud injected at the face. The excess fluid pressure in the ground caused an upward flow, and an upward thrust on the runway pavement, causing the runway heaving.
