Abstract: |
The loading on the tools of a TBM can usually only be estimated through the global thrust force, which gives a typical force of about 250 kN for 17" discs. The actual loading is however highly variable, with peak loads that can be many times the nominal load. In the present paper the development and implementation of a method is presented, which makes it possible to measure disc forces in-situ and in real time. It turns out that the measured forces are unevenly distributed over the area of the face and can be correlated with geological/geotechnical features in the face. Furthermore, a method is presented which makes it possible to document the face photographically. Single images or videos are combined to an overall image by means of digital image processing. The quality of the pictures obtained in this way can provide a significant improvement of the geological documentation of TBM drives. |
