Abstract
Soft clay soils are in many coastal areas, these soils generally have high compressibility and don't provide required bearing capacity. Various techniques are used to improve these soils. The stone column technique has been successfully applied for the ground improvement. A stone columns technique is one of the soil stabilization methods that is used to increase strength, decrease the compressibility of soft and loose fine graded soils, accelerate a consolidation effect, and reduce the liquefaction potential of soils. They are mainly used for stabilization soft soil such as soft clays, silts, and silty sand. Several research has been conducted on the behavior and performance of stone columns with various materials utilized as column filler replacing the normal aggregate. This paper will review extensively on previously conducted research on some of the materials used as stone column backfill materials, its suitability, and the effectiveness as a substitute for regular aggregates in soft soil improvement works. This paper also discusses the techniques and methods of construction of stone columns. The bearing capacity of stone columns, and a combination of both methods in reinforced and unreinforced modes are presented using scaled physical models. The effect of various diameters with various depths in ground also reviewed. Results show that using stone column improves bearing capacity of soft soils and decreasing settlement. Using geotextile as stone-column encasement increases the efficiency of stone columns significantly. Finally, some guidance and recommendations are provided on parameter selection for the study of stone columns.
