The stability of embankment is directly affected by Physical and mechanical properties of embankment fill. The physical mechanics parameters of embankment fill, such as elasticity coefficient, poisson's ratio, cohesive force angle of internal friction, to stable influence rule to the slope of embankment is discussed using the FLAC3D numerical analysis software. The conclusions give some references for the selection of embankment filling material in the process of constructing a highway.%路堤填土的物理力学性质直接影响着路堤边坡的稳定性,采用FLAC3D数值分析软件探讨了路堤填土的弹性模量、泊松比、凝聚力、内摩擦角等物理力学参数对路堤边坡稳定性的影响规律.研究结论对公路建设过程中路堤填料的选择具有一定的参考价值.
