A fast 3D tunnel analysis - ScienceDirect

Jan 01, 2003 · This chapter considers a 3D finite element analysis for predicting surface settlements. Results of such a 3D analysis are shown for the computation of surface settlements from a full excavation of a circular new Austrian tunnel method (NATM). A new method is presented, in which similar results are obtained from a much more simple 3D analysis.

Tunnel Excavation Cross-Section Optimization by FEM under

With the development of transportation, subway is more and more important to every city, but the security of underground railway track faces with serious challenges. Tunnel excavation cross-section types have rectangle, roundness, arch, composite one and so on. In the tunnel excavation under Feng-tian Road in Chongqing, we chose three cross-section types for obtaining optimal …

A Completely 3D Model for the Simulation of Mechanized

Mar 09, 2012 · 3D models of deep tunnel excavation in rock masses have been proposed by Cobreros et al. ( 2005) and by Simic ( 2005) for the Guadarrama Tunnel (Spain) and by Graziani et al. ( 2007) for the Brenner Base Tunnel. Both refer to double shield TBM excavation in squeezing rocks and both are finite difference models.

Tunnel Excavations in 3D FEM - MIDASoft

The stress state induced by construction of a shallow tunnel (secondary stress state) is three-dimensional (3D) in general. The correct simulation of the 3D load transfer, occurring ahead of and behind the tunnel face and resulting in transverse and longitudinal arching around the unsupported section at the tunnel face, is of particular importance.
