| Abstract: |
| Based on distributed optical fiber sensing technology and time series analysis, a method for predicting reinforced concrete expansion and cracking was proposed. The availability of this method was approved by electrical accelerated corrosion experiment. The results show that the distributed optical fiber sensing technology could acquire the concrete expansion and cracking information steadily and effectively. Moreover, the exact cracking moment and position could also be predicted precisely by using time series analysis. |
| Key words: reinforced concrete corrosion optical fiber sensor time series prediction |
