摘要
为了降低建筑结构的维修与维护成本 ,增加结构安全可靠程度 ,对建筑结构的健康状况的在线监测与评估就显得十分重要 .光纤传感器相对于传统监测手段具有体积小、与结构相容性好、灵敏度高、具有线性响应、信带宽、抗电磁干扰能力强、抗衰减能力强、安装方式灵活和可进行长期在线监测等特点 ,因此用于监测民用结构的研究非常活跃 ,新的传感器不断出现 ,并且已经开始在实际施工当中尝试进行如应变、应力、裂纹、振动等对结构安全至关重要的信息的监测 .根据用途对适用于民用建筑结构的光纤传感器进行了归纳分类 ,介绍了其原理、使用方法以及在应用过程中易出现的问题与解决方法 ,对光纤传感器在民用建筑结构中应用研究的发展方向提出了指导性观点 .
On line monitoring and evaluation of healthy conditions of civil buildings is essential for maintaining structural safety and lowering maintenace and repair costs. In comparison with traditional monitoring means, fibre optic sensors feature small volume, high sensitivity, linear response, wide signal band, strong electromagnetic interference resistance, strong anti attenuation capability, easy installation and long service life. Therefore, the research on their applications became very popular, and a new sensor came after another, and trials have been made with fibre optic sensors in actual construction projects for monitoring such information as strain, stress, crack and vibration essential to structural safety. With fibre optic sensors suitable for civil architecture classified according to their applications, the operating principles, uses, and possible problems and solutions of these snesors are discussed in detail.
