Abstract

<p> After an earthquake, it is necessary to quickly and accurately assess the damage to road bridges and determine their soundness and safety in service in order to open roads as soon as possible. Further efficiency and sophistication of post-earthquake surveys are expected to be achieved through the use of new technologies and other means. However, there are few cases in which the requirements for these technologies have been systematically organized, and it is difficult to say that new technologies have been proposed that are optimized for the needs of road managers and inspectors. In this study, a 3D laser scanner was used for a post-earthquake survey of a road bridge damaged by an earthquake as an example of the use of new technology. The detection accuracy of the acquired point cloud data was confirmed, and the possibility of replacing the post-earthquake survey based on visual inspection and the requirements for the new technology were discussed.</p>
