Abstract: A physical model test of a composite foundation in a steel cylindrical mould was conducted to investigate the consolidation behaviour of the composite foundation treated by the deep cement mixing (DCM) method. Pore water pressures at different locations in the untreated soft clay and the earth pressure and load acting on the untreated soft clay and the DCM column in the composite foundation model were measured throughout testing. Settlement, radial drainage behaviour and loading distribution and transfer were studied. The failure mode of the composite foundation was examined and failure of the composite foundation was largely attributed to the local failure of the DSM soil column.
