This report gives the results of an investigation into the ground movements caused by the construction of a deep trench through predominantly granular soils for the renewal of storm and foul water sewers in an urban area. Measurements of both surface and subsurface horizontal ground movements and settlement were made at various distances from the trench at two locations during and after construction. The effects of loading from construction traffic and changes in the method of construction at the two locations, on the magnitude and distribution of ground movement are reported.(A)
