| Popis: | This paper depicts the deployment of Ground-Based Interferometer Synthetic Aperture Radars for obtaining displacements and accelerations of El Tajo and Almonte Viaducts during their routine load tests. These Viaducts belong to the Highspeed Railway Network between Madrid and Badajoz, which represents a strategic infrastructure in Spain. Both Viaducts are concrete arches whose size as well as whose height over the reservoir posed a tremendous challenge for obtaining proper field data using traditional devices. The paper shows the gathered experience on the use of this technique for subsequent routine load tests. Jose Vicente Fuente Acknowledges the support ot the program Torres y Quevedo (PTQ). R. Chacón and C. Ramonell acknowledge the funding of Ashvin, “Assistants for Healthy, Safe, and Productive Virtual Construction Design, Operation & Maintenance using a Digital Twin” a H2020 project under agreement 958161. All authors are grateful to ADIF for the invaluable collaboration and openness during the execution of the load tests vis-à-vis all research performed within the railway network premises.
