Abstract
The behavior of stone columns of various arrangements was studied in the laboratory by using small-scale physical models. The experimental design was largely based on the unit cell concept and the cylindrical cavity expansion theory. In each case, a model scale stone column was embedded in a soft silty soil bed of respective strength by considering the ratio of column spacing to column diameter. Soil beds without a stone column were also loaded in order to evaluate the improvement in the load carrying capacity due to the stone column. The soil bed compaction energy was emphasized in each case to ensure that each unit was constructed consistently and accurately. The load carrying capacity of a stone column was found directly proportional to the undrained shear strength and inversely proportional to the spacing over diameter ratio of the columns. Thus the improvement in the load carrying capacity of a unit consisting of stone column and soil bed increased with and increasing undrained shear strength and decreasing column spacing over diameter ratio.
