摘要: Many of masonry arch bridges are ancient structures still in use within the transportation infrastructure, and they require a constant diagnosis their structural integrity. In last decades, non-destructive testing has been recommended for evaluation order to preserve historical character. this work, multidisciplinary approach assess arches is presented. A GPR survey Cernadela bridge was carried out using 250, 500 800 MHz antennas. The main goal obtain relevant unknown parameters such as inner ring stone thickness later analysis by analytical modelling. Photogrammetric methods were also employed provide precise external geometry bridge. Results show that it possible determine thickness, which can be valuable information engineers perform an exhaustive assessment load carrying capacity
