Abstract

The representative Limit State Design(LSD) codes, AASHTO LRFD and Eurocodes, are widely being applied when designing civil structures. However, these codes are only applying tunnel lining design and segments design for shield tunnels. Recently in Europe, the Eurocode 7 committee was trying to create a research group called EG12, but they reluctantly decided not to create EG12 since it could have an impact on some of the other Eurocodes(including Eerocodes 2 and 3). Still there is an effort to continue researching LSD for tunnelling. LSD method will become the norm for the field of civil structural design in the near future. Therefore, it is important to fully understand Eurocode7:Geotechnical design in connection with Eurocode 2 and Eurocode 3. In addition, it is essential to follow international research trends and also to research for application to tunnelling.
