Tunnelling induced ground settlements may have adverse impact on the structures that are above the ground level as well as adjacent to the excavations. In the present study, ground settlements caused by TBM tunnelling are determined in greenfield conditions, using a finite element method (FEM) based software, PLAXIS and parametric study is performed after validation of numerical model with empirical results.
