摘要
介绍了一种先进的分布式光纤传感器技术,即布里渊光时域反射计(BOTDR),在连续配筋混凝土路面(CRCP)中布置了BOTDR分布式光纤传感系统,对路面板中连续钢筋和混凝土应变进行实时监测。研究结果表明,BOTDR在公路桥梁等一些土木工程结构的健康监测中具有重要的应用前景。
As a kind of novel distributed fiber optic sensing technique, Brillouin Optical Time Domain Reflectometer (BOTDR) is introduced in this paper. The distributed fiber optic sensing system based on BOTDR is arranged on a continuously reinforced concrete pavement (CRCP), the strain of the steel and concrete in the CRCP is detected on-line. The experimental results show that the BOTDR technologies demonstrate a wide spectrum of applications in structural health monitoring.
