“…Various techniques of installation have been conceived for various types of columnar inclusions in a wide variety of soils such as loose sandy to soft compressible soils depending on technical ability, efficiency and local conditions. Effect of method of installation, cased and uncased holes, number of lifts and magnitude of compactive energy per lift given to granular piles and pile spacing were discussed by Madhav and Thiruselvam (1988).…”

In this paper, ground improvement techniques are used to mitigate liquefaction hazards. Granular piles are the preferred alternative due to several advantages. Granular piles improve the ground by reinforcing and adding density to the surrounding soil apart from providing drainage. Different mechanisms operate in the function of stone columns/granular piles in liquefaction mitigation, including Drainage, Storage, Dilation, Densification, and Reinforcement. This paper presents an overview of the use of granular piles as a liquefaction remedial measure for sand deposits. A brief description on liquefaction and the associated features is presented. A short discussion on various ground improvement methods available for liquefaction mitigation is discussed in light of the importance of granular piles. Different installation methods and design concepts for granular piles are presented. Various mechanisms of granular piles in mitigating the liquefaction potential of loose sand deposits are discussed and quantified in detail proving their effectiveness in hazard mitigation.

“…Several researches have been carried out to study the behaviour of stone column-reinforced ground over the past three decades (Madhav and Vitkar, 1978;Balaam and Booker, 1981;Alamgir et al, 1996;Poorooshasb and Meyerhof, 1997;Lee and Pande, 1998;Muir-Wood et al, 2000;Ambily and Gandhi, 2007;Elshazly et al, 2007;Krishna et al, 2007;Black et al, 2007;Madhav et al, 2008;Bouassida et al, 2009). Horizontal geosynthetic reinforcement sheets can be used in the granular columns to increase the load-carrying capacity as well as decrease the bulging of the columns (Madhav et al, 1994;Sharma et al, 2004;Wu and Hong, 2008).…”

“…Stone columns, one of the most commonly used soil improvement techniques, have been utilized worldwide to increase the bearing capacity of soft soils and reduce the settlement of superstructures constructed on them. Several researches have been carried out to study the behaviour of stone column-reinforced ground over the past three decades (Madhav and Vitkar, 1978;Balaam and Booker, 1981;Alamgir et al, 1996;Poorooshasb and Meyerhof, 1997;Lee and Pande, 1998;Muir-Wood et al, 2000;Ambily and Gandhi, 2007;Elshazly et al, 2007;Krishna et al, 2007;Black et al, 2007;Madhav et al, 2008;Bouassida et al, 2009).The degree of improvement of a soft soil by stone columns is due to two factors. The first one is inclusion of a stiffer column material (such as crushed stones, gravel,etc.)…”

Stone columns are considered as one of the well-accepted as well as cost effective ground improvement techniques for the stabilization of weak soil deposits. This paper discusses the results of a series of small-scale model column tests that were undertaken to investigate the behavior of lime columns reinforced with fibers.The tests focused on studying the effect of percentage of fibers used as reinforcement to the lime column, the diameter of column was varied in accordance to the diameter of test specimen. The effect of consolidation of soft soil due to inclusion of the stone columns on settlement response has also been included in the model. Plane strain conditions are considered for the loading and reinforced foundation soil system . It has been observed that if the soft soil is improved with reinforced lime columns, there is considerable reduction in the total settlement due to lime column itself. The increase of fiber percentage in the stone columns is effective for reducing the total settlement .Results from a series of laboratory model tests on unreinforced and reinforced lime column-improved soft clay with fibers have been presented. As compared to unimproved soft clay, the increase in load-carrying capacity under different improved ground conditions has been observed. Since introduction of fiber in lime improves its engineering behavior, unconsolidated undrained triaxial compression tests are conducted on clay samples with central lime-fiber core in order to explore the suitability of lime-fiber cores in stabilizing clay deposits. The results indicate that the deviator stress is improved by the placement of lime -fiber column.
