Aspects of Model Interaction in Mechanized Tunneling

ABSTRACT Underground infrastructures are becoming increasingly important components of modern traffic concepts worldwide. This includes, in particular, investigations of the stability of tunnel faces, material models for subsoil behavior, damage analysis of tunnel linings and supports as well as process-oriented simulation models for mechanized shield driving. Due to the strong interaction between the individual tasks in mechanized tunneling, the exchange of data and the interplay of components in simulation, the Collaborative Research Center SFB 837 has been established at the Ruhr-University of Bochum. In this paper a brief overview on the 14 sub-projects in the SFB 837 addressing one of the characteristic research areas in underground engineering is given. The main part of the paper deals with key sub-projects solely dedicated to the computer-supported integration, visualization and interaction of related models and information
