Ground-Based interferometer radars for load tests of long-span arch bridges

On the 15th of July, 2022, Professor Rolando Chacón and his team (Alejandro Rodríguez, J. Fuente, R. Fabregad, C. Ramonell) from UPC (↗️) presented ASHVIN in a publication in Conference proceedings at International Conference on Bridge Maintenance, Safety and Management 2022 (↗️). This publication is entitled “Ground-Based interferometer radars for load tests of long-span arch bridges. Case study: Almonte and El Tajo Viaducts, Extremadura, Spain”. 

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, representing a strategic infrastructure in Spain. Both Viaducts are concrete arches whose size and height over the reservoir posed a tremendous challenge for obtaining proper field data using traditional devices. The paper shows the gathered experience of using this technique for subsequent routine load tests.
