DOI: 10.1016/j.tust.2019.04.004

Abstract: Abstract In ultra-long-distance rock micro-shield pipe jacking, the pipe wall friction resistance is a key factor that determines the magnitude of the jacking force and the layout of the intermediate jacking stations (IJSs), whereas the… read more here.

DOI: 10.1038/s41598-025-12637-9

Abstract: During shield tunnelling, vertical ground displacement is significantly influenced by deviations in both jacking force and cutterhead torque. This study investigates the effects of deviations in these parameters on ground displacement via numerical simulations. On… read more here.

DOI: 10.3390/sym14071462

Abstract: An analytical formulation involving residual force is proposed to predict the displacement of an existing structure by simplifying the tunnel as an infinite Euler–Bernoulli beam resting on a two-parameter Pasternak foundation. The feasibility is confirmed… read more here.
