| Abstract: | Through widely investigating the damage of the concrete beam bridges, the material defect and concrete cracking are the main forms of damage that influence the durability and service life of concrete bridges. Based on researching the material defect and concrete cracking mechanism, strengthening routine inspection and maintenance is the main technical method to guarantee the safety and to prolong the service life of the bridges. |
