摘要
基于连续介质力学中关于大变形的理论，结合土力学的基本原理，建立了一个以位移为变量的一维大变形固结方程，在此基础上分析了太沙基关于固结的思想，进一步研究了大变形时饱和软粘土的固结性状，给出了大变形固结理论与常规小变形固结理论在描述方法、本构关系、固结系数定义等的不同，发展了一维大变形固结的计算方法。
Based on the large strain theory of continuum mechanics and the fundamental theories of soil mechanics, an equation for the 1-D large strain consolidation theory is derived with the displacement as its variable herein. The differences between the large strain and the small strain consolidation theories are revealed, such as the description methods, constitutive relation, definition of coefficient of consolidation, etc. The FEM of 1-D large strain consolidation is also developed.
