Numerical Investigation of Slope Stabilization Using Recycled Plastic Pins in Yazoo Clay

Geographically, at the center of Mississippi is a concentration High Plastic Yazoo Clay Soil (HPYCS). Shallow landslides frequently occur in embankments constructed with HPYCS caused by rainfall-induced saturation embankment slope. The traditional methods are becoming expensive to repair shallow slope failure. use Recycled Pins (RPPs) stabilize failures offers significant cost and construction benefit can be useful remedial measure for these types failures. current study investigates effectiveness RPP slopes HPYCS, using Finite Element Method (FEM). FEM analysis was conducted PLAXIS 2D software package. Three uniform varied spacings were investigated reinforce 2–4H:1V slopes. Reinforced stability analyses performed investigate applicability HPYCS. results indicated that provides shear resistance sloping Uniform spacing sufficient increases Factor Safety (FS) 1.68 2H:1V deformation less than 15 mm. combination increase FS 2.0 7
