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。
An advanced distributed optical fiber sensor technology, Brillouin Optical Time Domain Reflectometer (BOTDR), is introduced. In the continuous reinforced concrete pavement (CRCP), a BOTDR distributed optical fiber sensing system is deployed, Reinforcement and concrete strain real-time monitoring. The results show that BOTDR has important application prospects in the health monitoring of some civil engineering structures such as highways and bridges.
