The use of Geogrid steep-slope reinforced earth walls constructed using steel wall-surface material in road embankment work is spreading rapidly. However, many aspects of the installation of a guard rail in work of this kind are still not clearly understood. This paper introduces the results of a field test on a full-size embankment performed as a first step in making these points clear.The purpose of this experiment are as follows:(1) To study the effects of the installation of a guard rail on a Geogrid steep-slope reinforced earth wall(2) To study the effects of the installation of a guard rail on the GeogridTherefore, the following items were included in the experiment:(1) Measurement of the displacement of the reinforced earth wall and of the change in the horizontal earth pressure of the embankment when a static load and a dynamic load are applied to the guard rail(2) Measurement of the strain distribution of the reinforcing material when a static load is applied to the guard rail(3) Measurement of the state of the reinforcing material, and guard rail damage when a static load and a dynamic load are applied to the guard rail
