Installation of groups of stone columns in clay: 3D Coupled Eulerian Lagrangian analyses

This paper describes the results of three-dimensional (3D) finite element analyses investigating the installation effects of groups of stone columns in purely cohesive soils. Installation of stone columns is simplified to the insertion of rigid cylindrical elements with conical tips in a single homo...
