【摘要】：影响混凝土耐久性最重要的因素是钢筋锈蚀,而锈蚀的主要成因是氯离子侵蚀。每年全世界因钢筋锈蚀而导致的直接和间接经济损失巨大,因此,对钢筋混凝土中氯离子侵蚀监测有重要的科学和经济意义。光纤传感器较传统的电传感器而言具有小巧轻便、抗电磁干扰、外形设计灵活以及可埋入混凝土构件的任何部位进行实时、多点监测的优点。对国内外用于监测混凝土氯离子侵蚀的光纤传感器进行总结归纳并结合现有光纤传感技术对其目前存在的问题及发展趋势进行了讨论。
[Abstract]:The most important factor affecting the durability of concrete is the corrosion of steel bar, and the main cause of corrosion is chloride ion erosion. The direct and indirect economic losses caused by the corrosion of steel bars are enormous in the world every year. Therefore, it is of great scientific and economic significance to monitor chloride ion erosion in reinforced concrete. Compared with traditional electric sensors, optical fiber sensors have the advantages of small and light, anti-electromagnetic interference, flexible shape design and can be embedded in any part of concrete members for real-time, multi-point monitoring. This paper summarizes and summarizes the optical fiber sensors used to monitor the chloride ion erosion of concrete at home and abroad, and discusses the existing problems and development trend of the optical fiber sensors combined with the existing optical fiber sensing technology.
