Abstract: Because of the complicated reinforced mechanism and experimental measure, combining with the reinforced steep slope of embankment engineering, the field test of deformation monitoring has been carried out. In light of the properties of geogrids, numerical calculation is done by nonlinear finite element method. The results from experiment and calculation show that the settlement and horizontal displacement of the embankment laid by geogrids can be reduced and limited at large extent. Therefore, the embankment stability is pledged. The calculated results are consistent with the field measured data. Some factors influencing upon the deformation, including the length, elastic modulus and interval of geogrids, are analyzed. The larger the modulus is, the better the results is. The geogrids with length of 6.5 m and interval of 0.6 m are economical and effective.

Key words: embankment of steep slope, geogrids, finite element method, experimental test, horizontal displacement and settlement
