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%。
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.
