Abstract
Stone columns are considered as one of the influential soil-stabilising methods that can increase the strength and workability of soft soil foundations considerably. In order to enhance stone columns workability, in this experimental study, some laboratory tests were carried out on different columns. They consist of various gravel shapes and particles distributions and columns reinforced by steel fibre reinforcements as well. Some additional tests were also conducted on columns covered by an ordinary gravel mattress reinforced by geotextile. In addition, stone columns with diameters of 63 and 92 mm were tested with a length-to-diameter ratio of 5. The test results were compared with different shapes of geotextiles, such as routine (full-length sleeve) and ring shapes, as the encasing material. It has been observed that using the mattress, geotextile and steel-fibre reinforcements enhances the load-carrying capacity of them that provide a basis for reasonable predictions on their settlement behaviour.
