Abstract
The high-speed rail line between Madrid and Extremadura, crosses over River Almonte with a great 384 m arch made of high-performance concrete. The exceptional dimensions of the arch and the specific considerations of high-speed rail bridges, required using an innovative structural scheme in HSR arch viaducts, using two separate sections in foundations that join in an octagonal one in the central part of the arch.
The construction of the structure has already come to an end, and nowadays the final steps are being undertaken. One of these features, includes the installation of a service monitoring system, that will allow the control of the structure’s behavior during the service life of the viaduct, and its comparison with the theoretical deflections obtained during its structural analyses.
