A review of the geology for compensation grouting performance at Bond Street Crossrail Station

Bond Street Crossrail Station is one of 9 brand new stations, 8 of which lie subsurface within the Crossrail central section. These new stations lie along 21km of twin bore tunnels.

Bond Street is situated in Mayfair, the heart of London's West End. The station consists of two ticket halls constructed from diaphragm and contiguous walling techniques. The western ticket hall is situated on the site of 65 Davies Street and the eastern ticket hall is located on the site of 18–19 Hanover Square. The ticket halls are connected to two platform tunnels which run parallel to the south of Oxford Street and north of Brook Street by a series of ventilation ducts and access passages. The two running tunnels are connected to each other via five cross passages. Four of the cross passages are linked to the ticket halls via escalator tunnels. Figure 1 shows the location of the tunnels.
