结构健康监测的概念在过去几年中一直是研究的主题，特别是在土木和结构工程中，老化的基础设施是主要关注的问题。这些研究导致了开发和部署新传感技术的举措。由于建筑行业的恶劣环境和土木工程结构的大尺寸，这种传感器应该是坚固的，坚固的，易于使用和经济的。光纤布拉格光栅（FBG）传感器提供了一种可行的这种感测方法，与传统传感器相比具有许多优点。这些特性包括抗电磁干扰、重量轻、尺寸小、多路复用能力、易于安装和耐用性。本文报道了新加坡南洋理工大学土木与结构工程学院和电气与电子工程学院关于FBG传感器的多学科研究计划的一些结果。新型光纤光栅应变传感器已被开发并部署在公路桥梁上，用于测量动态应变、静态应变和温度。这些研究的结果表明，如果包装得当，FBG传感器可以在与民用基础设施施工环境相关的恶劣条件下生存。(c)2005爱思唯尔有限公司保留所有权利。
The concept of structural health monitoring has been the subject of research over the last few years, particularly in civil and structural engineering where ageing infrastructure is of major concern. These studies have led to initiatives towards the development and deployment of new sensing technologies. Owing to the harsh environments found in the construction industry, and the large size of civil engineering structures, such sensors should be robust, rugged, easy to use and economical. Fiber Bragg grating (FBG) sensors offer a viable such sensing approach with a number of advantages over traditional sensors. These include immunity to electromagnetic interference, light weight, small size, multiplexing capabilities, ease of installation and durability. This paper reports some results from a multi-disciplinary research program on FBG sensors involving the School of Civil and Structural Engineering and the School of Electrical and Electronic Engineering at Nanyang Technological University in Singapore. Novel FBG strain sensors have been developed and deployed on highway bridges to measure dynamic strain, static strain, and temperature. Results of these studies indicate that, if properly packaged, FBG sensors can survive the severe conditions associated with the construction environments of civil infrastructure.
