Finite element study of geosynthetic encased stone columns in sensitive soft clay
… soil. Ground improvement methods like stone columns were reported as not effective when installed in the sensitive soft clays. But mechanism of the un-effectiveness of the stone columns remains unknown because of lack of a suitable and simple model for simulating the stress-strain …

Numerical Simulations of Spread Foundations Supported on Stone Columns Using the Discrete Element Method
<p>The implementation of stone columns as a ground improvement technique has become more popular in geotechnical construction practice as a result of their ability to improve strength, stiffness and permeability characteristics of weak clayey soil deposits. There are several analytical and …

Estimating the effectiveness of stone columns in mitigating post-liquefaction settlement using Plaxis 2D
… post-liquefaction settlement and the effects of stone columns as soil reinforcement is a relatively less established field. Generally, simplified empirical methods are employed for settlement evaluations. However, they possess several limitations such as the influence of non-liquefiable layers, …

An investigation into using rammed stone columns for the improvement of a South African silty clay
… contaminated soils. Among these techniques, stone column technology which was pioneered in the 1950s' aimed at improving both cohesive soils and silty sands. Although the technique has been used successfully in many advanced countries, its application in South Africa is minimal. This limited …

The hybrid of floating stone column by numerical and physical evaluation
… by adopting a ground improvement technique. The stone column is one of the most effective and feasible techniques for soft clay soil improvement. Stone columns increase bearing capacity and reduce the settlement of soil. However, soft ground of more than 40 meters depth makes stone column …

A study on ground improvement using a combination of stone and concrete columns
Stone column is a cost-effective ground improvement technique that is typically employed for low-rise buildings and road embankments. This technique mainly uses naturally occurring materials as its load transferring medium. However, stone columns have some constraints because of the loose …

Collapse of stone column foundations due to inundation.
… has studied the behaviour and performance of stone columns confined and not confined by geofabrics and rigid piles, as deep foundations, in collapsible soil subjected to inundation. Laboratory tests were carried out, under controlled conditions of sand density and surcharge pressure, using six …

Design of Bridging Layers in Geosynthetic-Reinforced Column-Supported Embankments
… be induced by the new embankment load. The columns in column-supported embankments can be driven piles, vibro-concrete columns, deep-mixing-method columns, stone columns, or any other suitable type of column. A bridging layer consisting of several feet of sand or sand and gravel is also used …

DEM Study of a Single Stone Column in a Clayey Stratum
… directly considered in the design of aggregate columns. However, because the granular material friction angle is a fundamental design parameter used to estimate the bearing capacity of aggregate piers, these factors could play an important role in the mechanical behavior of isolated aggregate …
