摘要
针对预应力锚索检测的问题 ,在分析预应力传感器研究现状的基础上 ,提出了采用光纤 Bragg光栅传感技术进行锚索监测的新方案 ,详细介绍了光纤 Bragg光栅锚索预应力监测系统的工作原理及主要构成、进行了工程现场与常规的电测技术的对比实验。结果表明 :光纤 Bragg光栅传感器具有高的精度 ,抗干扰能力强 ,结构简单 ,长期稳定性高 ,实现实时。
Contraposed to the disadvantage of anchor monitoring, a novel fiber optic Bragg pre-stress sensor is adopted in this paper,based on the analysis of the using pre-stress sensors. At the same time, the principle and constitutes of novel system are presented in detail. With the compared experiment of the FBG senor and the common electricity sensor stuck on the applied site, the result show that the FBG sensors have a high measurement precision lever, good anti-interference ability and long-term stability, simple structure and it can realize a real-time and on-line monitoring.
