Abstract: In order to study the existing problems and technical requirements of a bridge detection in Kunming, and promote the further development of bridge detection technology, static and dynamic load tests are carried out on a bridge that has been used for a long time in Kunming. The results show that the overall condition of the bridge is good, the bridge detection and evaluation method needs to be improved and updated, and the intelligent detection method is less used in bridge detection. The research results enrich the bridge maintenance and detection methods, and can provide important reference for bridge maintenance and detection.
