Our state-of-the-art software enables us to perform transient (i.e. time-dependent) three-dimensional analyses.
The excavation of a tunnel is done either round by round or continuously by means of TBM. In either case, both excavation sequence and advance rate affect surface settlements and the loading of the support.
IGT compiles sophisticated transient 3D-models (e.g. for subway stations) in order to optimize excavation works with regard to their impact on surface buildings and to overall safety.
