Until recently, there were few well-documented case studies of circular shafts, which made it difficult to estimate reliable ground movements arising from such construction. Careful interpretation of field observations of ground surface settlement during construction of 27 circular shafts built for Crossrail, London Power Tunnels and Northern Line Extension, together with centrifuge model testing in the geotechnical centrifuge at Cambridge University, provides new insight into the ground movements arising from circular shaft construction.
