The finite element analysis of an embankment with a soft subgrade reinforced with geogrids is conducted in this paper. The calculation results show that geogrids have brought an obvious effects in reducing the displacement of a soft subgrade and the stress level of soil mass ,and eliminating the nonuniform settlement of embankment. The influence caused by the position of the embedded geogrids on the displacement and stress level of embankment is also analyzed herein.
