Segment Lining — Fiber vs Rebar Segments
Fiber vs Rebar Segments for segmental tunnel lining production and supply.
Fiber segments delete the cage shop, the cage logistics and the cover-related spalling — 40 kg of fiber replacing 110 kg of bars is typical where bending demands allow. The structural case is ring-specific (openings and cross passages often keep hybrid cages); the money case is this subtraction.
Formula
Note: Planning-level tunnelling estimate — actual TBM performance is set by detailed geotechnical baseline data, machine design and the contractor's means & methods. Use for feasibility framing only.
