This paper presents a new approximate solution to study the settlement of rigid footings resting on a soft soil improved with groups of stone columns. The solution development is fully analytical, but finite element analyses are used to verify the validity of some assumptions, such as a simplified geometric model, load distribution with depth and boundary conditions. Groups of stone columns are converted...
This paper presents a set of systematic 2D and 3D finite element analyses that study the performance of groups of stone columns beneath a rigid footing. Those numerical analyses show that the number of columns and their arrangement have a small influence on the load-settlement curves. Furthermore, a reanalysis of previous laboratory data available in the literature confirms the small influence of...
