Summary |
The aim of the project was to change the concept of segments used in tunnels built with TBM through the use of self-compacting concrete with fibers that increase the efficiency of processes, reduce costs and improve the final product. In addition to that, the project also aimed to develop a comprehensive design methodology for these new types of segments taking into account the dosage of concrete and the structural performance. Several small-scale and real-scale experimental programs were performed. New methodologies for the quality control of the fibre reinforced concrete were developed and existing ones were improved. |
