Abstract

Economic and safe tunnelling requires a continuation of the detail design into the construction
phase. Besides a prediction of the geological conditions ahead of the face a reliable prediction
of the behaviour of the compound system of rock mass and support (system behaviour) is
required. With the knowledge of the ”normal” behaviour of the system the measured
displacements can be compared to the predicted values in order to detect deviations in the
behaviour in time. An additional benefit of such a prediction is the determination of the required
overexcavation in squeezing rock and the continuous control of the tunnel stability.
To provide a reliable and accurate procedure for prediction of displacements the program
“GeoFit” was developed. It considers several options, including the installation of support,
sequential excavation, and non-steady tunnel advance.
