Abstract:

Stone columns (SCs) are widely used as an effective technique to enhance the engineering performance of poor soils. The process enhancement of soils using stone columns is accomplished by the consolidated acceleration of weak soils through shortened drainage paths, increasing the load-bearing capability and decreasing settlement by addition of robust granulated materials. Despite the existence of several methods for assessing the bearing capacity of reinforced soils, predicting the behaviour of stone columns is prone to peculiar challenges that require comprehensive analysis. This paper reviews previously published literature on granular columns and includes various efforts to analyse and model weak treated grounds comprised of partially or fully penetrated, single or collections of granular columns. The paper also compares the differences between the most common design methods for assessing the bearing capacity of stone columns. Finally, the review guides engineers on the procedures and considerations to apply during system design. Keywords: Bearing Capacity, Granular Piles, Stone Column, Failure Mechanism.
