Soil improvement by reinforced stone columns based on experimental work

Abstract

Methods for analysis of stability and deformation under static and dynamic loading are exported. Stone columns are installed using a process similar to vibro-compaction, except that a gravel backfill is used, and they are typically installed in slightly cohesive soils or silt rather than clean cohesion less soils. In the dry soils, a cylindrical cavity is formed by the vibrator that is filled from the bottom up with gravel/crushed rock. The purpose of this research paper is to provide a review on ground improvement for using reinforced stone columns in geotechnical engineering projects. There is special focus on how to performance and evaluate ground improvement using reinforced stone column for special purposes. The previous results indicated the reinforced stone columns significantly increase the bearing capacity and tension of the soil. Based on previous results, critical values were discussed and recommended.
