Abstract

This general report overviews the 37 contributions submitted to the theme on modelling and testing of tunnels and deep excavations in soft ground at the Symposium on Geotechnical Aspects of Underground Construction in Soft Ground - TC204 Cambridge 2022. A general discussion on the modelling and testing of the papers included in this session are presented together with the topical highlights of the submitted papers. The content of this theme clearly confirms that the research in the field of tunneling and deep excavation is closely collaborated with the tunnel and deep excavation industry. The topics of this session strongly connected to the current engineering needs of the tunnelling and deep excavation. Furthermore, tunnel engineering has received more attention than deep exaction judging from the submitted paper numbers. In particular, the stability of the tunnel face attacts the most interest in tunnel engineering. Generally, numerical modelling is the most popular method applied both in tunnel engineering and deep excavation. Centrifuge is the first choice of testing for tunnelling as well as deep excavation.
