Abstract
To model the NATM shotcrete method of tunnelling we apply both 2D and 3D discretisations. The more or less traditional 2D approach is computationally simple, but it requires certain assumptions about the so-called beta-factor to be made. Therefore we also perform 3D FEM analysis for comparison.
Attention is focused on a tunnel in sedimentary clay rock. This rock is heavily overconso-lidated and as a consequence it involves high horizontal stresses. The impact of high K0values on tunnel contraction and surface displacements is shown to be significant.
