...M. Ji; F. Li; Z. Qiu; H. Zhou; Y. Zheng This paper presents a numerical investigation of the dynamic behavior of geosynthetic encased stone column ( GESC ) improved ground in dry sand. A pressure-dependent multi-yield model was adopted for soils, and the geosynthetic encasement was incorporated...

...N. Rahman; M. Rokonuzzaman; A. Rahman; T. Sakai Ground improvement is essential when constructing on soft soils with low shear strength. While ordinary stone columns (OSCs) are commonly used, their effectiveness is limited in very soft soils due to inadequate lateral confining support. This is due...

... numerical analysis exploring the functionality of geotextile-encased stone columns (GESC) in sand slope stabilization. The research demonstrates that a GESC, optimally situated in the central region of the sand slope, enhances stability to an ideal level. Additionally, an upper threshold in geotextile...

...K. Liu; R. Qiu; P. Zhou; T. Wang; D. P. Connolly; J. Xiao Cinder gravel, a porous, lightweight, and durable volcanic byproduct, has the potential to be a sustainable and cost-effective alternative to conventional stone columns for ground improvement applications. Its use in soft soils, however...

...M. Ji; J. Wang; J.-J. Zheng; Y. Zheng This paper presents a numerical study to evaluate the contribution of geosynthetic to the shear strength of geosynthetic encased stone column (GESC) under direct shear loading conditions. The backfill soil was characterised using the linearly elastic–plastic...

...A. Gholaminejad; A. Mahboubi; A. Noorzad The present research focuses on the simulation of encased stone columns in a 2D state by utilising the coupled finite difference method (FDM) and discrete element method (DEM). The stone column material was modelled by DEM using irregularly shaped particles...

...S. Rajesh This paper presents the results of a numerical investigation performed to examine the time-dependent behaviour of fully and partially penetrated geosynthetic encased stone columns (GESC). The investigation studied the influence of geosynthetic encasement, the stiffness of the encasement...

...K. Ali; J.T. Shahu; K.G. Sharma ABSTRACT: Stone columns have proved to be a useful technique for supporting flexible structures resting on soft soils. However, in the case of very soft soils, stone columns have encountered excessive settlements due to insufficient lateral resistance offered...

...C. Yoo; D. Lee ABSTRACT: The geogrid-encased stone column (GESC) system, which increases the confinement effect, has been developed to improve the load-carrying capacity of stone columns. This paper presents the results of an investigation on improvement in load-carrying capacity and settlement...

...K. Ali; J.T. Shahu; K.G. Sharma ABSTRACT: The use of stone columns is popular as a ground-reinforcing technique for supporting flexible structures on soft to very soft soils. When a very soft soil improved by stone columns is loaded, the stone columns undergo excessive bulging, because the very low...

...) provided some suggestions for the design of geogrid-reinforced crushed stone columns. Alexiew et al. (2005) described a series of design principles, technologies and procedures for GECs and emphasised the importance of the tensile modulus of the geotextile that is used for column confinement...

...C. Yoo; S.-B. Kim This paper presents the results of a comparative study on different finite element modeling approaches for modeling geosynthetic-encased stone column-reinforced ground for use in rapid embankment construction. The specific models considered include: (1) an axisymmetric unit cell...

...S. Murugesan; K. Rajagopal Stone columns (or granular piles) have proven to be ideal ground reinforcement for supporting flexible structures such as embankments and storage tanks. Stone columns installed in very soft soils will have very low lateral confinement: hence they undergo excessive bulging...
