光纤传感技术运用于混凝土裂缝测量是检测混凝土结构损伤的一种有效方式。分析了该技术的原理,并通过混凝土模型实验,探讨了裂缝与光纤中心轴夹角为30°、45°、60°时裂缝宽度与光损耗的定量关系,对该技术的可行性进行了验证。
Optical fiber sensing technology used in concrete crack measurement is an effective way to detect the damage of concrete structures. The principle of the technique is analyzed. The quantitative relationship between the crack width and optical loss when the angle between the crack and the central axis of the optical fiber is 30 °, 45 ° and 60 ° is discussed through the concrete model experiment. The feasibility of the technique is verified .
