N2 - Geotechnical engineers dealing with embankment construction over soft ground encounter major challenges due to low bearing capacity and excessive settlement characteristics of soft soils. As a result, a wide range of technologies has been developed to support embankment foundations on soft ground. One such technology is the use of geosynthetic reinforced pile-supported embankments. In this paper, a numerical study is carried out to investigate the load transfer mechanism from the embankment to the geosynthetic and piles. Results show that a significant amount of embankment load is carried by the piles and the lateral effects are significant closer to the toe of the embankment, even though they are not appreciated in current practice. Four design techniques have been compared with the finite element analysis and results clearly indicate the inconsistencies in current practice.
