Paper presented at the ISRM Regional Symposium - EUROCK 2015, October 7–10, 2015
Paper Number: ISRM-EUROCK-2015-165
... taking the measurement accuracy into account, there were 3 4 mm movements at the surface. The maximum displacements of the extensometer measurement points were about 25 mm (E21024). Typical displacements were ±10 mm and varied according to the excavation sequences. Normally, displacements along the...

... and the initial state of stress resulted from previous studies, which included stress measurements and a global analysis of the results. The calculated and measured displacements along the complete excavation sequence were compared and, by using a back analysis process, the elastic moduli of the rock...

... tunnels constructed with the New Austrian Tunnelling Method (NATM) which uses complex excavation sequences and support measures like shotcrete and rock bolts. Furthermore, if major inhomogeneities and faults are present then simplified 2-D analyses may lead to results which are in significant error...
