介绍了一座斜交圬工拱桥的大规模监测装置，其中采用了一系列技术来测量桥梁在列车荷载下的应变和位移响应。光纤布拉格光栅，视频测量，振弦应变计，裂纹传感器利用电位计，和激光测距仪。本研究的目的是评估技术的测量性能的圬工拱桥，以促进未来的监测决策的资产所有者。比较了每种技术的特点和实用性，以及具体的监测数据。虽然大多数方法的监测数据相当一致，但由于误差或测量限制，确实存在分歧，并讨论了这种分歧对资产所有者的影响。在一般情况下，这项工作也证实了结构健康监测技术的潜力，提供深入了解砌体拱形结构的动态行为，特别是遗产结构，可能有一个复杂的历史损坏，其进展是感兴趣的业主。
An extensive monitoring installation of a skewed masonry arch railway bridge is presented, where a range of technologies were used to measure the strain and displacement response of the bridge under train loading. Fibre-Bragg Gratings, videogrammetry, vibrating wire strain gauges, crack sensors utilizing potentiometers, and a laser distometer are employed. The objective of the study is to evaluate techniques for measuring the behavior of masonry arch bridges in order to facilitate future monitoring decisions by asset owners. Characteristics and practicalities of each technique are compared, as well as specific monitoring data. While the monitoring data from most methods agrees reasonably well, disagreements do exist due to error or measurement limitations, and the implications of this disagreement for asset owners are discussed. In general, the work also exemplifies the potential of structural health monitoring technologies to provide insight into the dynamic behaviour of masonry arched structures, and in particular heritage structures which may have a complicated history of damage, the progression of which is of interest to their owners.
