摘要
针对混凝土结构施工和长期安全监测的要求,研制出一种适用于混凝土结构长期健康监测的埋入式白光干涉型光纤应变传感器。将所研制的光纤应变传感器埋入到混凝土模型梁内部,进行了静载试验和疲劳试验。试验结果表明:所研制的埋入式白光干涉型光纤应变传感器具有良好的线性度、灵敏度。经过200万次的疲劳试验后传感器仍性能稳定,完全能够满足混凝土结构长期应变监测对传感器的性能要求。
In the light of the needs of long-term health monitoring of concrete structures, a new kind of embedded white-light interferometric strain sensor has been manufactured. The sensors are embedded into concrete beams for tests. The results show that the white-light interferometric sensor has good linearity and sensitivity. After undergoing the fatigue test for 2 million circles, it is still satisfactory in performance, and capable of long-term structural health monitoring.
