| 摘 要： | 埋入式光纤应变传感器在混凝土结构的健康监测中应用日益广泛,但其有效寿命远低于结构的使用寿命,不能实现对结构的全周期监测。基于可更换的思路,提出了一种新型的传感器设计方案,通过对老化的主要应变传感部件(光纤光栅、基底和传输光纤)进行更新来使应变监测得以长期连续进行,从而简便可靠地解决了埋入式光纤应变传感器的耐用性问题。

| Abstract: | Embedded optical fiber strain sensors have been widely used in the health monitoring of concrete structures. However,the serviceable life of the sensors has been demonstrated significantly less than that of the concrete structure.Therefore,it is not possible for the sensors to monitor the strain within the whole life cycle of the structure.A new design aiming at the solution to this durability problem is presented,where the aged basic components of a strain sensor(optical fiber grating,substrate and transmi... |
