Red beds clay filling embankment of one expressway in south China were used as research object in this paper. Through laboratory test, the mechanical parameters of the filler were obtained, and the deformation characteristics of the slope embankment were contracted between the soil and the reinforced soil in the use of FLAC3 D software. The results showed that the vertical displacement (uneven settlement) and horizontal displacement effectively were inhibited, the stability of embankment were enhanced.%以南方地区某高速公路的红层高填路堤为研究对象,通过室内试验,获取填料的力学参数,在加筋与未加筋状态下,采用FLAC3D模拟高填斜坡路堤的变形特征.结果表明,加筋有效的抑制了路基的竖向位移(不均匀沉降)与水平位移,增强了路堤的稳定性.
