    The increased rigidity of vibro-replacement stone columns in liquefiable soils offers the potential for liquefaction mitigation. This paper proposes a laboratory method to facilitate an investigation of this parameter. Shear-wave velocity data are used to obtain the vertical load distribution between loose sand and gravel column in composite columnar triaxial samples under static and cyclic loading. Significant reductions in cyclic stresses applied to the loose sand are obtained, offering the potential for the optimization of the design of vibro-systems to include load share benefits.
