The　best　reinforced　scheme　for　laying　geosynthetics　on　high　embankment　is　investigated.　Based　on　the　limit　equilibrium　theory,　a　new　concept　is　applied　to　improve　reinforced　embankment　which　geosynthetics　can　raise　the　shearing　strength　of　soil　by　increasing　the　direct　stress　of　shearing　surface.　The　best　reinforced　scheme　methods　are　deduced,　and　a　method　of　ascertaining　the　best　reinforcement　scheme　using　computer　aided　search　of　circular　failure　plane　is　also　obtained.　By　the　stability　analysis　and　applied　best　reinforced　location　analysis　of　8　kinds　of　typical　reinforced　loess　embankment,　the　feasibility　application　of　methods　and　the　effect　of　best　reinforced　location　are　verified.
