On-Site Loading Test of Tunnel Lining Segments in Barcelona
Read how scientists from the Technical University (UPC) carried out loading tests during the construction of the “L9” two-level subway line in Barcelona, Spain. The engineers used a very complex test procedure for analyzing the loading capacity of steel fiber reinforced concrete tunnel segments.
Over 200 transducers were used for documenting the behavior of the tunnel segments at different pressures over a prolonged period of time. Due to the very complex test setup and the extreme accuracy requirements, selecting the right pressure transmitter was crucial to successful testing. Read how the engineers solved this task.
