Abstract

Masonry railway bridges make up a significant number of the UK railway network. These bridges require regular condition assessments by transportation authorities to identify and evaluate defects that can result in structural failures. Common defects in such masonry structures are spalling, crack, bulging, joint defects and loss of section. The conventional bridge examination process is highly dependent on visual inspection, that is, an inspector should be on site and, as a result, such inspection can cause health and safety concerns as well as traffic interruption for a significant period. Digital examination process can replace the visual examination and it can subsequently reduce the number of site visits, traffic interruptions, and health and safety concerns. It can eventually speed up the examination process and improve the efficiency of inspectors’ work. Terrestrial laser scanner (TLS) can be used to identify defects and analyse their severity on the surface of bridge structures. The point cloud dataset captured by TLS can be analysed using commercially available software packages to identify defects and assess their severity. However, a review of the literature reveals that despite the importance of masonry railway bridges, there is scarce literature focused on exploring and comparing different software solutions for the purpose of defect detection and analysis in such bridges. Therefore, this exploratory research aims to demonstrate the applicability of digital examination for masonry railway bridges through the application of TLS. This paper contributes to knowledge by establishing a practical basis to identify defects in masonry railway bridges using commercially available software tools.
