TBM DiGs is an international conference series that provides a specialized technological forum discussing and exchanging knowledge related to TBM works in difficult grounds. The series covers a wide range of topics, including characterization of difficult grounds, field observations and case studies, physical and laboratory tests, numerical modelling and techniques, treatments of difficult grounds, TBM design and installation, tunnel support design, monitoring and risk management. TBM DiGs 2019 is the fourth conference in this series.

TBM DiGs 2019 is jointly organized by several universities and organizations involved in the tunneling industry, is supported by the tunnelling community worldwide, and is focused on TBM tunnelling technologies. The conference organizers would like to welcome researchers and practitioners involved with TBM tunnelling to the TBM DiGs 2019 conference to share, to cooperate, and to progress.


Conference objectives and topics

The conference aims to bring together all who are interested in the use of tunnel boring machines in difficult ground, to review developments in the field over the previous two years, and to attempt to extrapolate for the near-term future. We anticipate that the conference will explore a great variety of topics.

Who should attend?

Those involved with the use of tunnel boring machines in difficult ground comprise a diverse community, including academic researchers, industrial scientists and engineers, government scientists, and policy makers. All are welcome to this conference, ranging from those just beginning to those with substantial expertise.

TBM DiGs 2019 will be an exciting conference that will provide the opportunity for participants to be able to meet others in the field, to exchange ideas, expertise and experience, and to renew and form new friendships and working relations. The conference is structured so that participants can learn from both formal and informal interactions, such as presented papers, posters and social events.
