摘要
采用非线性分析软件ADINA建立地基土体固结沉降的有限元模型,利用ADINA的非线性特性和特有的多孔介质材料,考虑地基土体沉降过程中的排水固结,对地基土体固结沉降过程和结果进行分析,研究如何运用有限元计算地基土体的固结沉降问题。
Using porous medium material and non-linear analysis of the ADINA, considering infiltration flow during the consolidation process of groundwork soil. This paper established finite element model of consolidation settlement of foundation soil by non-linear analysis software ADINA, analyzed the process and the results of consolidation settlement of groundwork soil, and studied how to calculate consolidation settlement of groundwork soil by FEM.
