A procedure for the design of precast tunnel segments for mechanical excavated tunnel lining in fiber reinforced concrete, without any traditional steel reinforcement, is presented herein. Both assisted by test procedure for particular loading situation is also proposed. Finally, a case study related to a precast steel fiber reinforced concrete segment is analysed in order to clarify the procedure and to show practically how to define the actions and to evaluate the interaction envelopes.

“…In general, FRCs are used mainly for pavements and shotcrete that are applied to slopes and tunnel supports. However, currently, FRCs are particularly used in the precast industry (Ferreira and Branco 2007;Walraven 2009;De la Fuente et al, 2012a) and in tunnel building projects (Gettu et al, 2004;Kasper et al, 2008;Chiaia et al, 2007Chiaia et al, , 2009Caratelli et al, 2001;De la Fuente et al, 2012b), as reflected in various papers presented in international workshops and conferences in recent years (RILEM 2004(RILEM , 2008(RILEM , 2012.…”

This paper presents research results regarding the distribution of steel fibers in concrete used to build precast tunnel segments for Line 9 of the Barcelona Metro. The fiber distribution was studied using the actual fiber contents obtained by means of crushed cores drilled from different points of three full-scale tunnel lining segments. A statistical analysis determined that the fiber content in the ends of segments tend to be greater than in the central zone. In addition, cores with a diameter of 150 mm were found to have a lower scatter in the fiber content than smaller diameter specimens. Finally, based on probabilistic approaches, a minimum of 11 cores is proposed to control the fiber content in FRC segments.

“…In some applications, such as precast tunnel segments, the possibility of totally or partially replace the traditional reinforcement with FRC allows several advantages not only in terms of cost reduction but also related to an increase of the quality and structural performance [32,26,9,15,10,29].…”
