Structural design calculation tool of Steel Fiber Reinforced Concrete (SFRC) segmental lining
Abstract: Segmental lining for a tunnel support system, for a shield on a tunnel boring machine (TBM) refers to the precast segments built in a pre-cast concrete manufacturing facility. Although steel fibers have been used in many tunnels worldwide, for most precast tunnel segment designs, rebar is still used for reinforcement mainly. The labor and material costs make up a large part of the manufacturing...

Structural design calculation tool of Steel Fiber Reinforced Concrete(SFRC) segmental lining
Abstract: Segmental lining for tunnel support in shield TBM method refers to the precast segment built in the factory. In most TBM tunnel segments, many rebar is used to reinforce concrete. So reducing the rebar cost is significant in TBM shield tunnel construction method. Therefore, reinforcing the steel fiber instead of rebar can improve economical efficiency as well as structural safety, which...
