In a series of short articles, we presented selected research results of the Collaborative Research Centre “Interaction Modeling in Mechanized Tunnelling” at the Ruhr-Universität Bochum in the journal tunnel in 2021. In this concluding part, the authors summarise their work, focusing on the transfer potential for a practical application in tunnelling.

Recapitulation

In 2010, the Collaborative Research Center “Interaction Modeling in Mechanized Tunneling” (SFB 837) has been is established by the German Research Foundation (DFG) at Ruhr University Bochum. The SFB 837 is currently the largest research group conducting fundamental research in tunneling-related topics worldwide.

The research goals of the SFB 837 are concerned with various relevant planning and construction aspects of the many components of the mechanized tunneling process. This includes

the characterization and modeling of the in-situ ground and the disturbed ground conditions in...
