Development of Sprayed Concrete Linings for London Underground Bond Street Station Upgrade Project, London, UK

摘要

Bond Street station is undergoing a major upgrade to increase capacity, improve accessibilityrnand create interchange with the new Crossrail station. It is one of the most complex sprayed concrete liningrn(SCL) tunnel design projects undertaken by London Underground. The design has had to address challengingrnconnections to and interfaces with the existing infrastructure requiring the use of binocular sections, anrnunderpass tunnel and a large cruciform junction. This has required significant design effort, maximizingrninnovation and utilisation of the latest technology including the use of fibre reinforced sprayed concrete forrnboth the primary and secondary linings.
