About the Project

Rail infrastructure deteriorates with time due to material fatigue, overloading, ground movement and environmental effects. This might affect the serviceability and structural integrity of rail assets, such as bridges, causing major socio-economic disruptions and occasionally life loss. Ageing masonry bridges comprise around the 50% of the UK and European rail stock and their structural assessment is particularly challenging. Traditional inspection practises and fragmented monitoring appear unable or impractical to ensure adequate maintenance on a national scale. Digitisation of civil infrastructure networks emerges today as an essential next step to address this challenge, offering opportunities to enhance our understanding of the structural deterioration mechanisms involved, and hence supporting decision-making for the maintenance of railway networks. 

This PhD research will explore the benefits of combining advanced sensing technologies with data analytics to enable automated civil asset management tools for resilient infrastructure, focusing on ageing railway bridges. The student will work on the processing and interpretation of field monitoring and lab tests data from two ongoing deteriorating bridge monitoring projects. Data science techniques will be applied, combining information from fibre optic strain and temperature sensors, acoustic emission sensors and high-sensitivity accelerometers. The analysis will contribute towards the development of early-warning, sensors-based, deterioration monitoring systems that will integrate machine learning, cloud data management and statistics. The student will benefit from the close collaboration with researchers from ASTUTE and AiPT at Aston University, the University of Cambridge, the University of California, Berkeley, engineers from Network Rail and industry partners. 

This PhD research combines elements from civil engineering, data science, systems engineering, information and communications technology, electronics and photonics. Applications from students with background or aspirations in any of these areas and with interest to develop their digital abilities are welcome to apply. Tailored training on Data Analytics and AI shall be provided.
