DOI: 10.1007/s10706-018-0752-z
Abstract: Stone columns are mostly designed to carry compressive loads. However, in some cases, the movement of soil mass can result in lateral deformations, and consequently shear stresses in soil and stone column. The study presented… read more here.

DOI: 10.1007/s12205-020-0349-y
Abstract: Compacted granular columns are commonly used to support embankments over soft soils. Using a reinforcement layer under the embankment causes the total stress to be further transferred to the column rather than soft soil, thus… read more here.

DOI: 10.1007/s40098-018-0342-2
Abstract: Analyzing instability in geomaterials in the form of shear localization using finite element discretization leads to erroneous results if the constitutive formulation does not contain any internal length scale. Thus, the solution becomes mesh dependent.… read more here.
