An Experimental Study on the Behavior of Precast Tunnel Segments Reinforced by Macro-Synthetic Fibers during...
Abstract: The use of fiber reinforced concrete in tunnel linings, with or without conventional rebars, has increased in the two last decades, especially in segmental linings. The design process of segmental concrete linings in ground conditions generally refers to temporary loading conditions (demolding, storage, transportation, grouting process and TBM thrust jack phase) as well as to the final...

Innovative Solutions for Sustainable Tunnel Segments
Abstract: The tunnelling industry continuously strives to reduce construction costs while finding more sustainable solutions. This seemingly contradictory requirement can be addressed by the benefits of macro synthetic fibre (MSF) reinforced concrete solutions. Experience from several projects has shown that MSF reinforced concrete segments exhibit robust, durable, and dependable behaviour even under...

Local splitting and crushing behavior under TBM hydraulic jacks
Abstract: During the lining construction process, high concentrated thrust jack forces are introduced in the segments leading to both high compressive stresses under the thrust shoes that can provoke a concrete crushing and tensile transversal stresses; the latter can cause cracks and, eventually, a splitting failure. In order to investigate the main mechanisms involved during either splitting or...

Optimized reinforcement for precast tunnel segments with macro-synthetic fibers
Abstract: The use of fiber reinforced concrete (FRC) in tunnel linings, with or without conventional rebars, has increased in the two last decades, especially in segmental linings. Nowadays there is a growing interest in the scientific community on macrosynthetic fibers for use in underground structures. Within this framework, the present study investigates the possibility of using macro-synthetic fiber...

Precast tunnel segments reinforced by macro-synthetic fibers during TBM opera tions: an experimental and numerical study
Abstract: In the scientific community and among designers there is a growing interest on macro-synthetic fibers for use in underground structures, especially for precast tunnel segmental linings. Segment reinforcement is generally designed according to the design actions on tunnel segments, resulting from segment transportation, placing process and ground pressure in the final state. In particular,...
