Field tests were m~d~ on two stone col~ns produced by the vibroflotation process, one cemented amd one uncemented. ~ e same critical load was obtained for the two col~mms, with lower settlements on the cemented column. The finite element analysis was m ~ e %o inves~__gate the stresses anl dlsplac~nents inside the columna~ as well as plasticity when the load Ix1~reases.
