It is need to understand concern with settlement of embankment and wall face deformation, strength of geogrid and earth pressure of back the wall, to recognize stability of geogrid reinforced wall with wall block used dry construction method.We were constructed the 8.0m test embankment of geogrid reinforced wall with wall block used dry construction method. The test embankment was set earth pressure gauges of back the wall and on base, strain gauges on the geogrids and settlement plates in back fill. It was observed deformation of the wall face, top of the embankment and settlement plates about one year.Next we were trying FEM analisys. This FEM analisys is used double contact point method, because it is able to think friction coefficient of soil and geogrid and wall block and geogrid, . In result FEM analisys of double contact point method is useful for geogrid reinforced wall with wall block used dry construction method.
