采用分布式光纤传感技术(BOTDA)和时间序列分析相结合的方法,对钢筋混凝土锈胀开裂程度进行监测和预测,并通过通电加速锈蚀试验对该方法进行有效性验证.结果表明:分布式光纤传感技术可稳定、准确地获取混凝土的锈胀信息,同时结合时间序列分析方法可有效预测混凝土锈裂时间和位置.
The method of combining distributed optical fiber sensing (BOTDA) and time series analysis was used to monitor and predict the degree of rust cracking in reinforced concrete. The validity of this method was verified by electrification accelerated corrosion test.The results show that distributed The optical fiber sensing technology can get the corroded information of concrete stably and accurately. Meanwhile, combining the time series analysis method can effectively forecast the concrete rusting time and location.
