AbstractThe behavior of isolated sand columns stabilized with lime and embedded in bed of soft soil of untrained shear strength cu between 16 – 19 kPa, is investigated. Holes in the form of columns 50 mm in diameter and 300 mm in length were excavated in a bed of soil and backfilled with sand mixed with various percentages of lime and cured for 7 days. A rigid circular footing 64.6 mm in diameter was placed on each column and loaded axially up to failure. The analysis of the model test results showed encouraging improvements of the load carrying capacity of the columns and significant reduction in the settlement over the conventional stone columns.
