Abstract

This paper presents 3D numerical analysis of a shallow tunnel with advancing face supported by horizontal glass fiber anchors. A hypoplastic constitutive model is used. The model is based on nonlinear tensorial functions and is developed without recourse to the concepts of elasto-plasticity theory. The influence of installation of anchors on surface settlement is studied for the Lainzer Tunnel in Vienna, which is currently being constructed according to the principles of New Austrian Tunneling Method (NATM). The numerical results are compared with the instrumentation data.
