Résumé

Road infrastructure is subject to increasingly demanding operating conditions. The loads stressing the bridges is increasingly high, which overloads the existing structures, many of which were designed with lower design loads. The high frequency of heavy vehicle traffic accelerates damage to the structure. Furthermore, other environmental causes (ice, de-icing salt, settling, temperature, etc.) make existing structures unsuitable. The security risk of bridges is most frequently raised by crack. The paper explored a digital and smart bridge crack system for improving the efficiency and risk factor for bridge security diagnosis. Artificial intelligence and deep learning will enhance the inspection of concrete bridge structures, and it will become the future trend of development.
