摘要
主要研究一种混凝土表面式的光纤光栅传感器的工作特性,应用光纤光栅的传感特性实现了对钢筋混凝土试件内部应变的测量,试件不仅就应用光纤光栅进行混凝土结构内部应变测量的技术、工艺进行研究,还对光纤光栅传感器进行了重复性实验,验证了其具有良好的一致性。同时,还考察了光纤光栅传感器的温度补偿问题,试验结果表明该方法具有较高的实用性。
The characters of a kind of surfaced fiber Bragg grating sensors on concrete is studied, the internal strains of steel reinforced concrete are measured by fiber Bragg grating sensor, Not only the technique and eraftwork are studied experimentally, but also the temperature compensation and the effect of repetition experiments of FBGS are investigated, the experiments results shows that the method proved with higher practicability.
