有限元分析加筋路堤软基的变形

FEM analysis on the deformation of soil foundation of reinforced embankment

结合Plaxis程序对加筋路堤软基的变形进行分析,通过对三种形式的路堤进行数值分析比较,得出了一些结论,分析结果表明,加筋能够很好的限制侧向变形,显著减少沉降和不均匀沉降,且立体加筋的效果要好于平面加筋。

By using the Plaxis FEM software, three kinds of embankments were analyzed. Based on the analyzed reinforced embankment, it was concluded that reinforcement can, ruduce the settlement as well as ensure more uniform settlement, and goecell was more effective than geogrid. Some useful conclutions were obtained which can been more referenced by engineering project.
