Abstract

Stone Columns were first introduced approximately 60 years ago as a technique for improving both cohesive soils and silty sands. Its construction involves the partial replacement of unsuitable soils with a pattern of compacted vertical columns of stone. In the settlement analysis software, Settle3, a Stress Reduction Method is used for computing the settlement under the composite stiffness of soil and stone columns. This study provides a settlement analysis of a case study with ground improvement using stone columns. The same model was created using a 3D FEM analysis software, RS3, to calculate the settlement. The results of the case study show a good agreement using both 3D FEM and the simplified settlement analysis using Settle3 software considering the same assumptions in both software. Also, the stress concentration ratio of stone columns and soil stiffness are also discussed in the models.
