ABSTRACT
The prediction of the magnitude and development of the expected displacements has a considerable impact on a large number of issues during tunnel construction.
On the one hand, excavation and support methods are influenced by the magnitude of displacements. On the other hand, the over-excavation has to be adjusted to the expected displacements to guarantee the clearance after stabilisation. In case of a misjudgement of displacements serious consequences have to be expected.
