1. Subject:
Analysis and verification of the influence of geological-geotechnical and mechanical parameters on penetration in TBM-Tunnelling in rock.
2. Aims:
- Evaluation of existing models
- Proposal for improvement for existing models
- Development of a new model (ALPINE MODEL)
3. Methods:
- Analysis of project data
- Analysis of results from laboratory tests on rock samples
- Operational modelling
4. Procedure:
- Processing of project data
- Laboratory tests on rock samples
- Feeding of data into existing models, particularly the GEHRING-Formula
- Development of additional features or improvement of existing features of the GEHRING-Formula
- Validation of established correlations and search for new correlations
- Development of a prototype software for the prediction of advance rates
