An Analysis of Pile-Soil Interaction under Embankment Load

The complex interaction between the pile and surrounding soil significantly affects the behavior of the piled reinforced embankment. In this paper, a 3D numerical model of piled reinforced embankment was set up to explore the development of the settlement of the pile and the surrounding soft soils during the embankment filling as well as the subsequent consolidation of the soil. The evolution of the pile axial force, the skin friction and the neutral plane depth was also studied. The results show that the settlement of the pile and surrounding soil, the pile axial force, the skin friction along the pile shaft and the neutral plane depth during the embankment filling and the consolidation process experienced a complicated evolution.
