Abstract

The prediction of surface and subsurface ground displacements and strains is an important element in the design of new underground construction in urban areas. A number of plane strain centrifuge tests were undertaken at the City University, London, to model the effect of a tunnel excavation in layered ground consisting of a moderately stiff clay stratum overlain by a thick stratum of medium dense sand and the interaction of tunnelling generated ground movements on pre-existing structures. Tunnelling was performed beneath a buried thin and high structure founded close to the tunnel crown. The purpose of the study was to assess ground movements and strains at different depths and the potential damage on the pre-existing structure.
