| Abstract | ||||
| Sand – gravel (SG) soil stabilized by cement kiln dust (CKD) in mixture reinforced by Glass Fiber (GF) as new piles body properties are tried to present the needed parameters for simulating pile reinforced sand slope on Plaxis 2D program. A numerical investigation by the Finite Element Method (FEM) was simulated on Plaxis 2D by modelling sand slope supported by mentioned piles under strip footing loads. The Piles material was simulated as SG – 30% CKD - 1% GF mixture parameters. On the other hand, numerical investigation was analyzed to adopt the settlement (S) improvement limits, and to obtain the needed force which safes sand slope stability by decreasing of lateral displacement (δ) and (S) to a desired value. It is clear that simulating sand slope with angle (40 º) under pressure (q = 280 kN/m2) is more critical. Piles with mentioned conditions found a solution for slope with the critical angle (40º) stability by saving the value of safety factor (F.S > 1.5). General indexes refer to the importance of increasing piles embedded length in stable layers according to the mentioned pile dimentions ratio. | ||||
