Monitoring Assessment Masonry Infrastructure

项目摘要

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

该项目涉及对历史悠久的维多利亚铁路桥梁和高架桥进行激光扫描、光纤应变监测和振动测量。总体目标是更好地了解砖石铁路基础设施的结构行为以及控制历史砖石的恶化过程，特别是在动态火车荷载下。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不清楚，因此，今天进行的维修工作实际上可能会对资产的整个生命周期产生有害影响。该项目将允许以同情的方式完成即将进行的修复工作，确保这些结构的未来安全，并确保英国铁路网络的资源效率。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工作，将其用途扩展到砖石结构。与历史英格兰、网络铁路和剑桥智能基础设施和建设中心 (CSIC) 的合作将成为结构工程的重要组成部分。 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查资源效率传感器和仪器结构工程
