  3D-Nonlinear Finite Element Analysis of Staged Shield-driven Tunnel Excavation with a Focus on Response of Segmental...

  Abstract: The complex and dynamic nature of shield-driven tunnel excavation, staged construction, segmental lining installation process, and tail-void grouting necessitate using detailed numerical modeling for predicting ground behavior and response of segmental lining. In this paper, results of three-dimensional advanced finite element modeling using DIANA program are presented simulating shield-driven...

  Impacts of Tunneling in Soft Ground on a Bridge Foundation

  Abstract: 6000mm diameter tunnel is proposed to be excavated under the road bridge using Earth Pressure Balance (EPB) technology. The effect of tunnel construction on the foundations of the bridge is evaluated for the most critical cases. Three-Dimensional (3D) Finite Element (FE) software, DIANA, is used to simulate the staged construction of the tunnel and potential ground loss. In summary the analysis...
