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。Corrosion of reinforcement is the main factor to influence durability of concrete, and the corrosion of reinforcement was mainly caused by chloride erosion.Huge economic loss was caused directly or indirectly by chloride erosion all over the world in every year.Therefore,it is significant to detect chloride erosion.Compared with traditional electricity sensor,optical fiber sensors （OFS） have many advantages such as small volume,electromagnetic stability and flexible shape,which can be embedded into any part of the concrete to achieve remote monitoring.Research actuality about OFS for chloride erosion detection was summarized, and discusses the current prob- lems and development trends of combining existing OFS for chloride erosion.
