Experimental Study of Failure Mechanisms of Soil Cement Columns under Embankment Loading
This paper describes the centrifuge model construction procedure for an embankment on a soft clay profile reinforced by Soil-Cement (SC) columns and presents preliminary results and observations of the ground and embankment responses. Centrifuge model corresponded to, in model scale units, a 12 cm embankment with a relative density of 80% underlain by a 23 cm soft clay layer. Three rows of floating SC columns with a diameter of 2 cm and spacing of 2.4 cm were installed below the embankment toe. The centrifuge modeling procedure including soil consolidation, SC column mix design, and their installation under the embankment toe is described in detail. The results indicated that the prominent failure mode of low-strength SC columns is tension-bending failure. In addition, it was observed that the embankment crest experienced large settlement due to lateral deformation of the foundation soil and SC columns.
