Concrete Bridge Damages and Safety Maintenance Technology

In the bridges´ entire life cycle, it is inevitable for bridges to be degraded and damaged because of the environmental factors and the conditions of usage. Taking more than 1500 concrete bridges in Beijing as the background projects, it is summarized that the typical diseases, the manifestations of functional damages and structural damages of concrete bridges. Among them, the functional injury accounted for 80% of bridge defects, and it exacerbated the deterioration of structural damage. Maintenance and Reinforcement technologies were used to a disease overpass bridge, in order to enhancing the durability and improving the bearing capacity of the whole bridge. The conclusion can be given that for ensuring the bridge usability, durability and prolonging the service life of bridge, it is significant to strengthen Bridge Daily Maintenance Management herein.
