ABSTRACT

Today, many geophysical methods are available, which support the exploration of a tunnel route before tunnelling commences. Some have also been used during tunnelling for many years. Among them, seismic methods account for the largest share in both the number of tunnel applications worldwide and the success rate of contributing to geological exploration.

Since deep and long tunnels harbour considerable geological uncertainties, continuous measurements are increasingly becoming urgent to obtain a complete forecast. It is precisely these tunnels that are being driven by more powerful TBMs, which require a smooth and fast course of all measurements on the job site. Moreover, flexible operation and analysis of results is required. Modern systems are mastering these requirements more and more. Case studies are presented in which operational as well as data-analytic aspects are compared and discussed. Likewise, new trends in the interaction between tunnelling and geophysics will be presented.
