摘 要: 本文从连续介质力学的基本原理出发,用拉格朗日描述方法建立了物质构形上的饱和土体二维大变形固结控制方程,并给出了相应的矩阵表述,为大变形固结有限元分析打下了基础。 Based on the principle of non- linear continuum mechanics,the equation and its corresponding ma-trix form governing three-dimensional large- strain consolidation of sarurated soil have been developedwith material deseription method in this paper, which provides a basis of further analysis of large-strainconsolidation by FEM.
