Abstract

Data are presented of the behaviour of model walls in overconsolidated clay, tested in a centrifuge at 125 g. The removal in flight of a heavy fluid in front of the model wall was used to simulate excavation in front of a prototype in-situ construction. Measurements of bending moment, prop force, wall deflection and ground movement were made as pore pressure transducers responded to imposed variations in groundwater conditions. In particular two walls, one unpropped and one propped, are investigated. The consequential deformations of the unpropped wall, and the bending moments in the propped wall, are described and discussed in relation to the anticipated behaviour of a full-scale construction.
