Experimental Study of the Concrete Structure Performance Degradation of Songhua River Bridge
Songhua River Bridge is an important large concrete bridge engineering in China. Because it is located in complex environment, the reinforcing steel rust, freeze-thaw, artificial damage and washout will result in performance degradation of the concrete structure. The paper firstly invested the climatic environment and local corrosion environment. Then, according to the environment characters, studied the structure endurance degradation regulation combining the laboratory simulation tests and natural exposive tests. Made a group of concrete test specimens according to the true construction field material mixture ratio. The field experiments include air exposure, half soaking and full soaking tests. And the laboratory tests include freeze-thaw test, salt aspic test, chloride ion penetrant test, carbonization test, etc. Through test research, the paper gripped the degradation regulation of bridge concrete property. Then constructed the bridge concrete endurance degradation model, established the theoretical foundation for predict the large bridge service life.
