The change in index, mechanical properties and settlement behavior of improved soils with 13 cm diameter packed drains is quantitatively discussed. The settlement plates were placed before constructing the sand mat and packed drains. Therefore, the settlement behavior throughout the whole process, including loading pre-load, can be measured. The natural water content and the compression index decreased about 20%, the unconfined compressive strength increased about 10% and the pre-consolidation pressure increased about 70% by using driven packed drains with a sand mat. The estimated settlement increased about 15% by taking into account the effect of sample disturbance and the prediction accuracy of the final settlement greatly imroved.
