Horizontally Layered and Vertically Encased Geosynthetic Reinforced Stone Column: An Experimental Analysis

Because of the smaller confinement neighbouring soil in very weak soils, carrying capacity stone columns may not substantially increase. Geosynthetics can be used to reinforce by employing vertical encasement or horizontal layers. In present study, large-scale laboratory investigations were carried out evaluate efficacy and layering geosynthetics on performance behaviour soft clay. A series tests for a geotextile with an equal distance throughout height column (the total is ‘L’); over only top half (i.e., 0.5 L from head considered column); bottom (0.5 centre foot column). Tests also form vertically encased (VESCs) that employed various lengths L, 0.75 0.25 L). The conducted three different diameters columns, i.e., 50 mm, 75 100 mm. As per findings, utilisation reinforcing layers enhances capability columns. Moreover, because their interlocking frictional actions aggregates decreases lateral bulging comparison was performed find effectiveness types reinforcement, it observed VESCs full-length higher tensile strength mm diameter most desirable arrangements among all.
