STRUCTURAL BEHAVIOR OF SFRC TUNNEL SEGMENTS DURING TBM OPERATIONS (2007)
The paper addresses precast tunnel segments for the new Line 9 of Barcelona Metro. After the experimental determination of the material properties, non-linear analyses allowed to study the structural behavior of the tunnel segments under TBM thrust jack forces during construction process. The paper focuses its attention to the advantages coming from the use of Steel Fiber Reinforced Concrete (SFRC) in terms of crack control and bearing capacity. Finally, Ultra High Performance Concrete (UHPC) has been investigated to study if this material is suitable for the application in tunnel segments.
