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 tes...

Construction on weak subsoil is a reoccurring challenge for engineers nowadays, which various different solutions are available. Geosynthetics getting more and popular one of their most widely used application reinforcement. Several types geosynthetics can be used, the well-known vertical drains geogrids. Prefabricated accelerating consolidation in oversaturated soils with high water content as...

This paper presents a review of combined vacuum consolidation and surcharge preloading which is arguably more sustainable approach to soft-soil ground improvement than other strategies in reducing post-construction settlements. Vacuum consolidation has become more prevalent with technological developments in vertical drains, pumps and geosynthetics. Satisfactory vacuum pressures can be sustaine...
