Modelling Soil Structural Interaction during Tunnel Excavation
1 Day Awareness Seminar - Thursday, 23rd February
This seminar will focus on numerical modelling of the complex interaction between soil and structure during tunnel excavation. This is a major talking point currently, with over 26 miles of tunnels being built under the UK’s capital city as part of Crossrail and numerous London Underground Station Upgrade projects. Ensuring that the tunnels are correctly designed is essential to ensure the safety of those involved in the tunnelling operation as well as ensuring that life above ground carries on without interruption.
The event will focus on modelling of the soil-structure interaction behaviour in tunnel construction, with an emphasis on sprayed concrete lining. This seminar will provide guidance on the following topics.
- Time dependent nature of sprayed concrete material properties
- Variability in material properties
- How to reduce unnecessary conservatism when designing a sprayed concrete tunnel lining
- How to ensure your design is code compliant.
Other modelling issues associated with tunnel construction such as compensation grouting and building damage will also be discussed and there will be presentations from leading experts from Mott MacDonald, UnPS, Keller Holding GmbH, Oxford University, etc.
We are also pleased to have Professor Helmut F. Schweiger from Graz University of Technology giving a keynote presentation.
In addition to addressing the issues relating to modelling tunnel excavation, a number of case studies will be presented during the seminar. The day will be concluded with a panel discussion chaired by Professor David Potts on the different methods of representing sprayed concrete that are currently used in industry.
Who should attend?
We hope to see the seminar attract interest from tunnelling and geotechnical engineers, designers, FE/FD modellers, project managers and constructors who want to learn more about the latest developments in modelling the tunnel excavation process.
The event is open to both members and non-members of NAFEMS.
Members of BTS can attend this seminar at the discounted members registration fee of just £50 plus VAT.
If you wish to register for this event, please provide your BTS membership number and invoice details, to firstname.lastname@example.org.

The BTS is an Associated Society of the Institution of Civil Engineers (ICE)
Formed in 1971 to provide a forum for meetings and discussion on tunnel-related matters, the BTS also publishes industry guidelines and codes of practice;conducts training courses to advance the education of tunnelling professionals;actively supports the recruitment of young people to the industry; acknowledges excellence in tunnelling; sponsors and supports industry conferences; and advises Government and the general public on the tunnelling industry.
The British Tunnelling Society maintains a leading role in the development of the tunnelling industry to promote the safe, efficient, sustainable, and technically advanced design, construction and use of underground space.
The BTS calls on a long tradition of tunnelling in Britain to continue industry-wide development of this vital field of civil engineering. The society was a key player in the founding of the International Tunnelling Association (ITA) in 1974 and represents the UK on its General Assembly.
Individual and corporate members are working on underground projects of all types andpurpose throughout the world.
The BTS supports a Young Members branch, who are active in schools and universities in promoting tunnelling as a career.
There is an opportunity available for your company to exhibit at the seminar, giving you maximum exposure to a highly targeted audience of delegates, who are all directly involved in simulation, analysis, and design.
