Experimental study on soil improvement with stone columns and granular blankets

摘要: Stone column is one of the soil stabilizing methods that used to increase bearing capacity and decrease settlement soft soils. Reinforced unreinforced granular blankets are now being utilized overcome problems In this research, stone columns, blanket, a combination both in reinforced modes were studied using scaled physical models. Results show column, improves Using geogrid as reinforcement geotextile stone-column encasement increases efficiency columns significantly. Additionally, case around stress concentration ratio will well its rigidity capacity.
