Based on the FEM method,the deformation rules of the sand embankment above the soft foundation are studied by the FEM analysis model.The vertical deformation,the lateral deformation and the vertical stress on the base layer of the pavement are discussed by the FEM method.Thence,the de-formation rules and the stress distribution are determined,in addition,the sensitivity of the parameters is discussed.%通过有限元法建立考虑地基软土固结沉降的填砂路堤变形分析模型，研究了软土地基上填砂路堤的变形规律。通过分析计算对填砂路堤的竖向变形、侧向变形、基底竖向应力分布规律的特性进行研究，得到了填砂路堤的侧向变形、竖向变形的分布规律与影响因素，并讨论变形对各参数的敏感性。
