Modelling Soil Structure Interaction during Tunnel Excavation

Conventry, UK, February 23rd 2017


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.

  1. Time dependent nature of sprayed concrete material properties
  2. Variability in material properties
  3. How to reduce unnecessary conservatism when designing a sprayed concrete tunnel lining
  4. 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.

Dr Andrew Mar from UnPS, author of the upcoming NAFEMS publication entitled ‘Modelling Sprayed Concrete Lined Tunnelling’ will also be presenting on his book, with a discount available on purchase of the publication exclusively to those who attend.

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.
