Abstract: Damage inspection and cable force test were discussed for an expressway partial cable-stayed bridge in a practical project in this study. Furthermore, the causes of damage were analyzed. The results showed that the repair and maintenance measures should be taken. Finally, the repair and maintenance measures were proposed for the damage of the expressway partial cable-stayed bridge. The cable forces were tested at 2 year (or less) intervals. And the health records of cable forces should be established to provide reliable scientific basis for the analysis of stay cable distribution, structural condition assessment, as well as maintenance and management of the bridge. The box girder of the bridge should be repaired, reinforced and the degree of inclination of the pylons be regularly measured. Anti-corrosion measures should be taken on the various components of stay cable systems. Grease should be filled in the anchorage components. The change in the relative position between the HDPE pipes and the guide pipes should be focused on. These results could also provide a reliable reference for the damage inspection and maintenance of similar bridge structures.
