摘要
文章采用比奥特固结有限元法,基于费尔哈斯特的非线性模型,对某高速公路软土路基的固结变形、孔隙水压力的变化与消散过程进行了有限元模拟,以期为类似软土工况下的公路施工提供参考。
Based on Verhulst nonlinear mode and Blot consolidation finite element program,the FEM analysis was conducted for consolidation deformation, changing and disappearance progress of pore water pressure for highway soft soil subgrade, which could be taken as reference for highway construction under similar soft soil construction condition.
