Abstract
Uncertainties in the geological and ground models, as well as simplifications in the design in general lead to an inaccurate design of underground structures. Observations during construction are required to optimally adjust the construction method to the real ground behaviour. Increased safety, reduced costs and risk are the targets of an observational
approach. Absolute displacement measurement with geodetic methods nowadays is common on many tunnel sites. The information contained in the measurement data can be used not only to assess the stability of an underground structure, but also to predict final displacements and the ground quality ahead of the face and around the tunnel.
To assist the engineers on site to optimally exploit the information contained in the displacement monitoring data, various tools have been developed, including an expert system, which allows an automatic assessment of changing ground conditions ahead of the face. In addition monitoring is is an essential part the safety management on site. The potential of
advanced data evaluation methods is shown
