Case Study Webinar Modelling in TBM Tunnelling
- Design Approaches
April 29, 2021 (Thu)
- Time 1(GMT 7am): SGT 3pm / AEST 5pm
- Time 2(GMT 11am): BST 12pm / CEST 1pm / CAT 1pm / GST 3pm / IST 4:30pm | Duration : 60 min

TBM tunnel linings are jointed, and this introduces particular modeling requirements. Because joints between segments are the weak points of TBM linings and concentrated, translational and rotational deformations are among the main factors which should be considered.

This presentation covers the most typical aspects of TBM modeling in particular related to geometrical connections. Through extensive international experiences, the speaker will highlight best practice associated with the design and execution phase, whilst encompassing the real cases demonstration.
