The paper describes analyses solution of cut in the highway. There have been used three methods of making construction: reinforced wall with HDPE geogrids, soil nailing and retaining wall 20 meters long. AASHTO standards have been used for checking stability of reinforced wall and soil nailing, while retaining wall is based on EN 1997-I standards. ...
