Plain and fibre-reinforced sprayed concrete - Part 2: tunnels

In Part I of this paper a material model for sprayed concrete was implemented into a structural finite element analysis package. In this part the model was used to analyse sprayed tunnel linings. Circular tunnel sections made of plain or fibre-reinforced sprayed concrete, with or without steel reinforcement, were analysed. The load-carrying capacity, mode of failure and cracking pattern were predicted. The results indicated that the effect of the reinforcement on the performance of the lining depended on the loading condition being designed for. When a horizontal loading was applied, steel-bar reinforcement combined with fibre-reinforcement enhanced the load-carrying capacity and deformability of the structure. When both horizontal and vertical loads were applied on the whole of the tunnel section, the fibres had no effect and the steel bars had a negligible effect on the behaviour of the sprayed concrete tunnel. It was recommended that both plain and fibre reinforcement should be included in the structures.
