本文对铁路行业结构监测的最新研究进行了回顾，特别关注基于应力的解决方案。在对有碴铁路轨道的机械性能进行简要分析后，概述了最常见的监测技术。特别注意应变计和加速度计，它们需要在轨道上准确安装位置。然后将这些类型的解决方案与另一种基于光纤使用的现代方法进行比较。此外，还深入讨论了研究铁路车辆与轨道之间相互作用的数值模型的演变。这些模型用于验证实验设备并预测传感器的最佳位置。希望这篇综述文章能够激发这个不断扩展的领域的进一步研究活动。
A review of recent research on structural monitoring in railway industry is proposed in this paper, with a special focus on stress-based solutions. After a brief analysis of the mechanical behaviour of ballasted railway tracks, an overview of the most common monitoring techniques is presented. A special attention is paid on strain gages and accelerometers for which the accurate mounting position on the track is requisite. These types of solution are then compared to another modern approach based on the use of optical fibres. Besides, an in-depth discussion is made on the evolution of numerical models that investigate the interaction between railway vehicles and tracks. These models are used to validate experimental devices and to predict the best location(s) of the sensors. It is hoped that this review article will stimulate further research activities in this continuously expanding field.
