ABSTRACT
The development of high-speed railways brings numerous opportunities for economic growth and improved transportation networks. In the United Kingdom, the construction of the High Speed 2 (HS2) railway is a flagship project aimed at enhancing connectivity, increasing capacity and reducing travel times. However, the construction will impact existing infrastructure along the route. This paper presents an overview of the ground movement assessment conducted on eight existing masonry arch bridges in West London affected by settlement due to construction of HS2 twin bore tunnels. This work has provided valuable insights into the potential challenges and risks associated with tunnelling under a major city. The findings underscore the importance of thorough structural assessments and implementing appropriate interventions to ensure the safety and resilience of existing bridge infrastructure above new tunnel construction.
