Title: | Design according to MC2010 of a fibre-reinforced concrete tunnel in Monte Lirio, Panama |
Abstract: | This paper discusses the possibility of using precast tunnel segments in fibre-reinforced concrete without traditional reinforcement. The case study of a hydraulic tunnel in Monte Lirio, Panama, excavated with a tunnel boring machine (TBM) by SELI S.p.A., has been analysed. The segments were designed according to the draft of Model Code 2010. In order to achieve the required performance and to optimize the structural behaviour, three different types of steel fibre were considered in the research. The design was backed up by full-scale tests on precast segments. In particular, 18 full-scale tests were performed, including point load tests simulating the thrust of the TBM and bending tests. The results show the good behaviour of the elements and indicate the fibre-reinforced concrete suitable for the precast elements. |
