Monitoring and Assessment of Masonry Infrastructure

该项目涉及激光扫描，光纤应变监测和振动测量的历史，维多利亚铁路桥梁和高架桥。总体目标是更好地了解砖石铁路基础设施的结构行为和管理历史砖石的退化过程，特别是在动态列车荷载下。还应制定维护和缓解策略。这些拱形砌体结构的长期行为尚未得到很好的理解，因此，今天进行的维修工作实际上可能对资产的使用寿命产生不利影响。该项目将使即将到来的建筑以一种同情的方式完成，确保这些结构的未来，并确保英国铁路网的资源效率。监测和传感技术在结构工程中越来越受欢迎，该项目将继续开展重要的工作，将其应用扩展到砌体结构。与历史英格兰，Network Rail和剑桥智能基础设施和建设中心（CSIC）将成为该项目的重要组成部分，并将确保该项目始终保持与其旨在受益的现实世界基础设施资产的联系。EPSRC的相关研究领域包括：建筑环境机械结构和系统的性能和检测资源效率传感器和仪器结构工程

This project involves laser-scanning, fibre-optic strain monitoring and vibration measurement of historic, Victorian railway bridges and viaducts. The general objective is to achieve a greater understanding of the structural behaviour of masonry rail infrastructure and the deterioration processes that govern historic masonry, specifically under dynamic train loading. Maintenance and mitigation strategies shall also be developed.The long-term behaviour of these arched masonry structures is not well understood and, as such, repair work that is undertaken today may in fact have detrimental effects over the lifetime of an asset. This project will allow upcoming restorations to be done in a sympathetic manner, securing these structures for the future and ensuring resource efficiency on the UK rail network.Monitoring and sensing techniques are becoming increasingly popular within structural engineering and this project will continue important work needed to extend their usage to masonry structures.Collaboration with Historic England, Network Rail and the Cambridge Centre for Smart Infrastructure and Construction (CSIC) will form an important component of the project and will ensure that it always retains its links to the real-world infrastructure assets it aims to benefit.Relevant EPSRC research areas include: Built environment Performance and inspection of mechanical structures and systems Resource efficiency Sensors and instrumentation Structural engineering
