  Simulation on Shield Behaviour at a Sharp Curve by Kinematic Shield Model

  Abstract: Due to ongoing development of shield tunneling technologies, usage of more complicated tunnel alignments is increasing. Excavation at a sharper curve needs proper steering of shield machines. Shield behavior is controlled usually by copy cutter, articulation mechanism, and jack force and moment. Then the kinematic shield model, which can take shield operation including the above shield...
