本文报道了40个加固保护光纤布拉格光栅传感器（FBG）在全玻璃纤维增强聚合物复合材料公路桥的集成和评估。据报道，这座桥是欧洲第一座全纤维增强复合材料桥。这座桥的一个独特之处是它是由拉挤玻璃纤维复合材料部分建造的，这些部分是在现场粘合的。在桥梁的装配和粘接阶段，FBG被集成在指定的截面上。光纤传感器的主要功能是提供：（i）桥梁的实时和现场应变和温度数据;（ii）应变数据，以验证全复合材料桥梁的设计规范。介绍了该桥的试验室试验和现场试验结果。后者包括用一辆30吨的卡车装载桥梁。(C)2004 Elsevier B.V.保留所有权利。
This paper reports on the integration and assessment of 40 ruggedly protected fibre Bragg grating sensors (FBGs) in an all-glass fibre reinforced polymer composite road bridge. This bridge is reported to be Europe's first all-fibre reinforced composite bridge. A unique feature of this bridge was that it was constructed from pultruded glass fibre composite sections, which were bonded on site. The FBGs were integrated at specified sections during the assembly and bonding phase of the bridge. The primary functions of the fibre optic sensors were to provide: (i) real-time and in situ strain and temperature data from the bridge and (ii) strain data to enable the validation of design codes for the all-composite bridge. Results from laboratory tests and field trials during the proof testing of the bridge are presented. The latter included loading the bridge with a 30 tonne lorry. (C) 2004 Elsevier B.V.
