【 摘 要 】

In order to realize real-time dynamic monitoring, the reinforcement corrosion was monitored using acoustic emission technology. The three stages of reinforcement corrosion could be responded by the analysis of acoustic emission parameters and waveforms. And the results indicated that acoustic emission could monitor the corrosion process in reinforced concrete structure. Early warning of steel bar corrosion damage can be realized.
