    Comparative Study of Settlement Performance of Stone Column and Vertical Drains: A Review
    (Springer Science and Business Media Deutschland GmbH, 2025) Kapile, P.; Sridhar, G.
    The process of building stone columns through weak soils, specifically soft and ultra-soft clays, is known as “vibro replacement.†An integrated foundation support system with reduced compressibility and enhanced load bearing capacity is formed by the stone column and the intervening soil. Stone columns in cohesive soils easily discharge excess pore water pressure, causing settlement to occur more rapidly than in clay without stone columns. Literature has shown that stone column has the tendency to bulge due to less in-situ lateral stress of soil which results in reduced effectiveness and increased settlement of stone column. Surcharging, a prevalent preloading method for strengthening weak ground, involves applying additional load through soil embankments. In the context of ground improvement, surcharge preloading is commonly used. Prefabricated vertical drains play a crucial role in expediting the consolidation process of soft clay deposits when employing preloading as a ground improvement technique. This paper presents a critical review of the settlement performance of stone column and preloading with prefabricated vertical drains as it is of utmost importance in ground improvement works. A case study comparing the settlement performance of stone column and preloading with prefabricated vertical drains revealed that latter technique is more suitable for extremely soft soil. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.
