Transport Infrastructure SHM Using Integrated SAR Data and On-Site Vibrational Acquisitions: “Ponte Della Musica–Armando Trovajoli” Case Study

This work presents the first results obtained by applying in situ and remote-sensing methodologies to monitor Ponte della Musica-Armando Trovajoli located Rome, within activities of WP6 “Structural Health Monitoring Satellite Data” 2019-21 Reluis Project. In particular, use Differential Synthetic Aperture Radar (SAR) Interferometry (DInSAR) measurements provided a spatial map displacement investigated infrastructure corresponding time-series, with aim monitoring deformation phenomena, focusing on local scale analysis, which produces suitable for urban damage assessment. The DInSAR have been integrated identification dynamic characteristics bridge, performed through an experimental campaign ambient vibration carried out October 2020 local-scale definition engineering geological setting foundation soil. subsoil bridge is constituted more than 50 m recent alluvial deposits resting Pliocene stiff clay acting as bedrock. A substantially stable behavior structural elements has observed based analysis both satellite velocimetric data. case represents good example about how integration sensors remotely sensed data exploitation detailed knowledge regarding on-site conditions represent key factor sustainable infrastructural can support planning maintenance safety management.
