Preliminary Insights from Surveys of Bridges at High Scouring Risk in West Piedmont

This study focuses on thirteen existing bridges of different structural typologies, located in West Piedmont (in the area under the jurisdiction of the Metropolitan City of Turin) and founded in different soil types. All of them have been previously classified as at high or very high hydraulic risk. For this reason, they are potentially subject to severe scouring, with detrimental effects on the structural behaviours and the seismic performance of the whole system. The visual surveys reported and discussed here aimed at a preliminary evaluation of the conditions of both the superstructure and the foundations. Particular attention was paid to the identification of signs of potential degradation phenomena, also in comparison with the available information from past in situ surveys. The results of these investigations highlighted some interesting cases that will be further addressed in the framework of the PNRR Spoke 7 “CCAM, Connected Networks and Smart Infrastructures” – WP4 “Resilience of Networks, Structural Health Monitoring and Asset Management”
