Abstract Precast segmental linings for shield tunnels experience substantially different loading conditions during storage, tunnel boring machine (TBM) advancement, synchronized grouting, and long-term service. This study presents a comparative finite-element assessment of conventional reinforced-concrete segments (CRCS) and recycled-fiber reinforced-concrete segments (RFRCS) incorporating 0.3% by volume of recycled tire-derived steel fibers together with conventional reinforcing bars.
