Abstract
Currently there is no uniform and consistent documentation of unexpected standstills
available, which can be applied during the excavation of tunnels with tunnel boring machines (TBM).
Such a documentation and evaluation would be helpful for the estimation of risks, costs and the
advance rate for future tunnels excavated with a TBM. An approach for a documentation of
unexpected standstills of hard rock tunnel boring machines, such as open gripper TBM, single shield
TBM and double shield TBM, was developed at Graz University of Technology. This paper shows
the results as well as the benefits of a detailed and continuous event documentation during tunnel
excavation. The new approach can be taken as a basis for future documentation of unexpected
standstills in TBM tunnelling.
