Developing methods for the interactive and collaborative exploration of alignments in tunnelling by processing digital planning data.

In this subproject, methods for visual representation and interactive evaluation of different alignment in tunnelling are developed. For the planning of tunnel alignments, the process of selecting a preferred alignment is currently a very cumbersome and manual process. It involves the consideration of a multitude of constraints, such as ground behavior, existing structures, and functional requirements. The evaluation and selection of the preferred alignment is then dominated by the results of technical and economic aspects. Finally, an evaluation of planning variants also requires an indicative cost estimate, which will consider results of cost structure in traffic tunnels from preliminary work.
The subproject aims to improve the current methods by supporting the study of alignments through digital and interactive methods. Through a more efficient and interactive planning process it is expected that more possible solutions can be investigated and can lead to an optimal solution. The main milestones of the project are:

  • Collocation of constraints for tunnel alignments
  • Rule based compliance checking for alignment constraints
  • Criteria for the evaluation of tunnel alignments
  • Interactive Exploration of tunnel alignments
  • Real-time based evaluation of interactions chains

The aims are supported by methods for the modelling, evaluation, and adaption for interaction chains, which have developed in the former phases 1 & 2 of the subproject. Especially, the use of interactions between various and interdisciplinary analyses are intended, such the prognosis of settlements using numerical simulations (subproject C1), the risk assessment for existing building structures (subproject D3) or the simulation of logistic influences during the excavation process (subproject C3).
