| Abstract: | To master the corrosion of reinforcing steel bar in reinforced concrete bridge-structures,the steel corrosion detection technology was researched by the method of test and finite element,based on wave theory,and the corrosion steel bar was chosen as the object. Results show that the detection technology is feasible in locating and recognizing steel corrosion,the detection technology has good practicability for its relatively high measurement precision; and the detection technology can be used in the locating and recognizing steel corrosion of reinforcing steel bar in reinforced concrete bridge structures. |
