Abstract

<p> In the maintenance and management of highway structures, various platforms have been proposed to spatially integrate and utilize various types of information on a 3D model. By building a platform, information on different structures such as bridges and pavements can be managed centrally using location information. On the other hand, it is difficult to construct a platform for complex structures such as special bridges because it is difficult to create a detailed 3D model, and there are also distortions and lack of location information in the inspection records. In this study, we proposed a new 3D modeling method for special bridges that changes the level of detailing for each member, and a method of integrating inspection and repair information and models by regularizing location information, and constructed an information integration platform suitable for use in maintenance and management. The visualization and spatio-temporal analysis of the information obtained from the platform were conducted, and the usefulness of the platform for maintenance management was clarified.</p>
