  • Abstract Shield tunneling has been widely used to construct the subway in order to reduce interfering with the surface traffic. In this study, elastoplastic finite element method is applied to analyze the interaction on parallel shield tunnels in soft clay. Plane strain eight node isoparametric elements are adopted and Mohr-Coulomb criterion is used for simulating the elastoplastic stress-strain and undrained behavior of soil. Numerical analysis is carried out to investigate the distribution of settlement and moment of tunnel lining during the closure of tail voids. The numerical results using “SPECTROM-32” under plane strain condition were compared with the results from centrifuge model tests.
    In addition to the results compared with centrifuge model tests, this analysis and evaluations are also carried out following parametric study, which investigates the effect due to (C/D) ratio, (d/D) ratio, Young’s modulus and cohesion.
