The paper deals with an analysis of the settlement of a tank. The tank has a diameter of 18.6 m and a volume of 1760 m3. The subsoil consists of soft sandy clays and clays of low to medium plasticity. The tank has been founded on a slab of a thickness of 0.2 m. A consolidation layer of compacted gravel of a thickness of 1 m was created immediately below the foundation slab. The soft subsoil was improved using the stone columns. The stone columns were installed using vibro-replacement bottom feed technology. The stone columns were created in a square mesh of a dimension of 2 x 2 m and 3 x 3 m. The settlement of the tank was computed using Fine Geo5 geotechnical software. The improvement of the subsoil was taken into account using three models. The first model took into account the subsoil below the foundation slab without any improvement. The second model took into account the homogenization of the subsoil without considering the compaction of the original subsoil between the stone columns. The third model also took into account the compaction of the original subsoil between the stone columns. The results of the analysis showed that the compaction effect causes an improvement of oedometer modules of about 1 - 2.8 times depending on the boundary conditions. The final settlement of the tank is significantly smaller when the compaction effect of the original subsoil between stone columns is taken into account in the calculation. In this case, the requirements of serviceability limit state, such as final settlement and non-uniform settlement, were fulfilled. The results of the deformation analysis allowed optimization of the stone columns dimensions.
