摘　　要：本文用物质描述方法，给出了饱和土大变形固结控制方程的矩阵形式．在此基础上，建立了基于初始构形的大变形固结增量有限元法，并对非线性的增量有限元固结方程的求解进行讨论，引入了自修正迭代算法．he equations governing the large-strain consolidation of saturated soil have been developed in matrix form with material description method in this paper.The finite element analysis in incremental form corresponding with material coordinate for large-strain consolidation theory of saturated soil is also established. Finally,the methods for solving non-linear finite element consolidation equations are discussed and a new method-self-correcting iterative approach is proposed in this paper.
