Abstract
The target of present paper was to determine the influence of stone columns in alluvial deposits of Tuzla area. The settlements versus time and depth, excess pore water pressure dissipation and consolidation time were studied by finite element analysis using Plaxis software. An undrained analysis was carried out for alluvial soils, and a drained analysis for stones and the compacted embankment soil using Mohr-Coulomb’s criterion. The results of this study indicate that, stone column has a remarkable influence on decreasing settlements and accelerate the consolidation time. Also, the stone column model designated by 15 m height has significantly reduced settlement and consolidation time.
Keywords: Alluvial soil, embankment fill, Plaxis, stone column.
