| Abstract | ||||
| Piled-embankment system is a ground improvement technique that can provide a solution for supporting the embankment over soft clay deposit. The main aim of this paper is to study the behavior of piled-embankment system over soft clay layer. A series of full-scale numerical modeling for the problem under investigation are studied using elasto-plastic Finite Element Modelling (FEM) program (2D PLAXIS V. 8.6). The studied parameters include the height of the soft clay (H), shear strength of the soft clay soil below the embankment (cu), relative length of piles (L/H), relative pile’s spacing (S/D), pile’s diameter (D) and the relative thickness of embankment (h/H). Each series was performed to study the effect of one parameter while other parameters were kept constant. The results showed that, using piled-embankment system on a soft clay deposit has a significant effect in reducing the settlement with time. It has been found that, the settlement of the embankment on a soft clay layer is reduced by as much as 77% of its initial value in the case of embankment without piles. | ||||
