“…Researchers showed that the optimum stone columns spacing giving maximum performance improvement is 2.5 times diameter (Dash and Bora 2013b). For large projects, it is preferable to conduct field experiments to calculate the optimum of stone columns spacing, considering the soil bearing capacity and the foundation settlement (Baviskar et al 2018;Dheerendra Babu et al 2013;Rao et al 2011;Suriya et al 2017).…”

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 stonecolumn encasement increases the efficiency of stone columns significantly. Finally, some guidance and recommendations are provided on parameter selection for the study of stone columns.

“…Below the encasement, there was a bulging collapse, fully enclosed columns minimise the strain by 80%. It has been proven to be very successful in increasing the bearing capacity in a vertically laden column to utilise a variety of geosynthetics as part of an encasement [20][21][22][23][24][25][26][27][28][29].…”

Stone columns are being used to reduce soft soil settlement and increase load-carrying capacity. Since there is inadequate lateral support from the local native soil, soft soil undergoes excessive settlement under vertical loading. This issue is effectively resolved by suitably encasing stone column material by geosynthetic with significant axial stiffness, which provides the required additional confinement reported in the literature. In the current study, an effort has been made to examine the load settlement behaviour of the dual-layered geosynthetic-encased stone column (DL-GESC) under vertical loading. In order to simulate the behaviour of stone column-reinforced soft soil, a FEM analysis was performed using PLAXIS-3D and three-dimensional (3D) models made utilising the unit cell idealisation technique for a single column. The stone column diameter, spacing to diameter (s/d) ratio, and encasement layers were varied to determine their influence on load-settling behaviour. The vertical load-carrying capacity of the ground was significantly improved when an additional layer of geosynthetic encasement was inserted into the stone column as compared to SL-GESC. Improvement of 15–25% was observed for the analysis of a single column installed in soft clay, according to the result obtained. Improvement ratios have been discussed in detail for various encasement conditions.
