Effect of area replacement ratio on the bearing capacity of dune sand and sodium silicate column in weak soil: A numerical study
The numerical analysis was conducted to study the effect of area replacement ratio on the bearing capacity of sand columns reinforced with 8% sodium silicate as an additive to increase their stiffness. The theoretical analysis was done using the finite element method (Plaxis 3D Foundation) to actual foundation dimensions for both floating and end-bearing sand columns. The analysis was carried out by using a model test of sodium silicate sand column with different diameters (0.3 m,0.5 m, and 0.7 m) or (Ar) area replacement ratio (0.071,0.196, and 0.38). The results show that the values of bearing capacity ratio are in the clay soil with an undrained shear strength of 30 kPa, which are 1.33, 2, and 2.82 in floating type and 1.41, 2.68, and 2.88, in the end, bearing type at area replacement ratio values (0.071, 0.196, and 0.38) respectively.
