Collaborative Research Center 837 - Interaction Modeling in Mechanized Tunneling

Subproject C4 develops simulation models for the numerical analysis of the excavation of the ground and the transport of the excavated material in Earth Pressure Balance shield machines driving through strongly variable ground conditions. The models provide an in-depth understanding of the fracture and fragmentation processes in the ground, the loadings acting on the excavation tools, and the transport and mixture processes and the pressure distribution in the excavation chamber. The dependencies on the geological conditions, the machine design and the soil conditioning are explored to identify potentials for improvements of the cutting wheel design and the machine technology.
