COGGE Webinar – 12/15/22: Geotechnical Challenges and Innovations in London Crossrail Construction
The talk focused on some of the challenges of creating tunnels in the complex geology beneath central London, whilst also preventing overlying buildings from being damaged by subsidence. Some innovations will be described, ranging from a novel approach to compensation grouting for protecting buildings, tunnelling directly beneath and through piled foundations, to fibre optic strain measurement to improve understanding of the behaviour of sprayed concrete tunnel linings.
