The effectiveness of pvd installation in bauxite residue soil by using plaxis 2d for settlements analysis

The construction of an embankment on soft soil always leads to settlements. Bauxite residue soil has similar behaviour to clayey soils which consider as soft soil. This study focused on the effectiveness of Prefabricated Vertical Drain (PVD) installation in bauxite residue soil for settlements analy...
