Seismic Imaging from a TBM
Seismic monitoring from the head of a tunnel-boring machine (TBM) enables improved assessment of the risks associated with the tunnel-boring process. The monitoring system provides a live image of ground conditions along the trajectory followed by the TBM and detects local heterogeneities such as boulders, foundations, and other obstacles that commonly pass undetected using local geotechnical t...
متن کاملInfluence of Geological Conditions on Measured TBM Vibration Frequency
This paper examines TBM vibration as a source of information about geological conditions. An EPB TBM was outfitted with accelerometers to monitor vibration during excavation of the University Link light rail tunnel project (U230) in Seattle Washington. Impact-response testing of the TBM indicated that significant signal over a wide range of frequencies transfers from the cutterhead where vibrat...
متن کاملMulti-labeled image classification by TBM active learning
The Transferable Belief Model (TBM) is well adapted for knowledge representation, especially for complex systems. In this contribution, the TBM is used as a basic tool of an assistance system for image collection classification. The first part of the system, which is completely automatic, models all available knowledge provided by the already labeled images in order to structure the unlabeled o...
متن کاملA Hierarchical Fusion of Expert Opinion in the TBM
We define a hierarchical method for expert opinion aggregation that combines consonant beliefs in the Transferable Belief Model. Experts are grouped into schools of thought, then opinions are aggregated using the cautious conjunction operator within groups and the noninteractive disjunction across. This method is illustrated with a realworld dataset including 16 experts.
متن کاملDesign Optimization of TBM Disc Cutters for Different Geological Conditions
A novel optimization methodology for the disc cutter designs of tunnel boring machines (TBM) was presented. To fully understand the characteristics and performance of TBM cutters, a comprehensive list of performance parameters were investigated, including maximum equivalent stress and strain, specific energy and wear life which were closely related to the cutting forces and profile geometry of ...
