The (**Figure 9**) shows the horizontal displacements along a vertical section for various attack sections R.

The maximum horizontal displacement Uh is the edge of the excavation to tend towards zero displacement at a considerable distance from the tunnel. With a difference between the displacements, values of every driving section R compared to another.
