| 摘要: |
| 针对现有预测模型中参数难以确定，导致预测精度不足的问题，采用分布式光纤传感技术对混凝土锈胀全过程进行实时监测，并基于监测数据对解析模型中的关键参数——铁锈膨胀率进行反演算，建立了可动态更新的钢筋混凝土锈胀全过程预测模型. |

| Abstract: |
| In the existing prediction model, the difficulty in determining the parameters could result in the deficiency of prediction precision. A method for dynamically correcting the parameters of the prediction model was illustrated. Based on the distributed optical fiber sensing technology, the whole progress of the expansion was real time monitored. According to data obtained via distributed optical fiber sensing technology, the key parameters of analytical model and corrosion expansion rate can be inversely calculated, which can help establish the dynamic updating prediction model of the whole progress of the concrete expansion. |
| Key words: reinforced concrete corrosion distributed optical fiber dynamic updating prediction |
