  • The research described in this thesis focuses on the consolidation behaviour and vertical bearing capacity of soft soil ground improved by Deep Cement Mixing (DCM) method. The soft soil ground modelled in this study may support relatively light structures, reclaimed fills or road embankments. Firstly, an axisymmetric physical model (Model 1) test was carried out to investigate the consolidation behaviour of soft soil ground installed with a single DCM column. The surface settlement, excess pore water pressures at different locations in the soil, and pressures carried by the soil and the DCM column were all measured throughout testing. This model test revealed that the DCM column behaved as a vertical drain partially, which suggests that the DCM column might be regarded as a parti...
