  • According to the structural, under-compressible, unsaturated and anisotropic characters of loess, loess was regarded as unsaturated soil, its 3-D consolidation equations were derived based on unsaturated soil theory, and its consolidation deformation characters were analyzed by FEM.It is pointed that compressed subgrade settlement deformation appears "sag" shape, its maximum settlement lies in embackment center, embackment shoulder settlement is minimum, and 1/3~2/3 of embankment high appears outward "extrusion" tendency; stress change tendency is inward and downward increasing, and minimum shear stress lies in slope toe; for unsaturated soil, after instantaneous loading, its surface settlement contains instantaneous settlement and soil mass consolidation settlement, and the former is main deformation.Analysis result shows derived unsaturated loess 3-D consolidation equations can well simulate and analyze the consolidation deformation of loess embankment, and its application prospect is quite good.
