Deformations of Subway Tunnels Induced by the Overcrossing Jacked Box Tunnels [PDF]
Symmetry, 2021 The rectangular utility tunnels have been increasingly built in urban areas in recent decades. In this paper, a case of jacked box tunnels built closely over-crossing the existing subway tunnels in Suzhou, China, is presented. The tunneling-induced deformation of the subway tunnels is measured and analyzed.
