Abstract: Piled reinforced embankments are increasing widely used in soft soils due to their rapid construction, low costs, small total and differential settlements and high stability. Soil arching developed within the embankment is the definitive factor influencing the behaviors of the embankments while the pile-soil relative displacement is regarded as the most important factor to affect the evolution of soil arching during soft soil consolidation. In this study, an axis-symmetric numerical model of piled reinforced embankment was set up to explore the characteristics of soil arching during the embankment filling as well as the subsequent consolidation. Based on the analyses, the equal settlement plane elevation was determined. Furthermore, the evolution of the pile axial force, the skin friction and the neutral plane depth was also studied. The results show that the pile-soil relative displacement significantly influences the soil arching. The pile axial force, the skin friction along the pile shaft and the neutral plane depth experience a complicated evolution.
