Geosynthetic-reinforced pile-supported embankments, as an economic and effect construction technique to reduce total and differential settlements and enhance load transfer efficiency for embankments, have been widely used in soft soils. Most studies have been done so far to investigate this embankment system under static loads. However, highway and railway embankments are subjected to cyclic loading. The behavior of this embankment system under cyclic loading is not well known, therefore, it deserves further research. In this study, based on a scale test, the fainant element method (FE model) incorporated in the 3D was adopted. A local cyclic load was applied on the top of the model and the deformation and pressure on the load-transfer platform and the tension in the geogrid under cyclic loading were monitored and analyzed. The numerical analysis shows that the cyclic load increased the differential settlement and miner the arching effect under cyclic loading and the lower load frequency has higher damage of arching effect.
