摘    要:利用ADINA有限元软件,采用摩尔-库仑模型,对非软弱地基路基的沉降进行了模拟计算。考虑路堤逐级加载过程,得出非软弱地基路基的沉降时间曲线和部分沉降规律,即:路基的沉降变形主要发生在施工期间,其工后沉降相对较小;路基面的竖向变形主要来自于地基的沉降,路堤堤身的变形量相对较小,对于黏性土填料约占总沉降量的0.5%。

关 键 词:路基沉降  修正剑桥模型  修正的分层总和法

Abstract:This paper has used ADINA finite element software and Moore-coulomb model to simulate and calculate roadbed settlement deformation of non-weak foundation.Considered the embankment gradually loading process,settlement-time curve and part of settlement regularity of non-weak foundation is concluded,namely,subgrade settlement deformation occurs mainly during the construction period,the settlement after their work is relatively small;the vertical deformation of the subgrade surface is mainly from the settlement of the foundation,the amount of the dike embankment deformation is relatively small,for clayey soil,packing accounts for about 0.5% of total settlement amount.
Keywords:roadbed settlement  modified Cambridge model~ correctional layerwise summation method
