The aim of this project is to gain understanding of ground behaviour around tunnels in the Sydney region, how the ground interacts with fibre reinforced shotcrete tunnel linings, and how changes in material performance affect risk to users and the reliability of the tunnel structures. These aims will be met by a combination of field and laboratory experiments and theoretical modelling. The outcome will be a rational and reliable design method for shotcrete lined tunnels in the Sydney basin.
