摘要
在给出饱和二相土壤介质的动力有限元分析基本方程的基础上，论述了考虑土壤弹塑性效应分析的一般方法，并以此为基础编制了土壤与结构相互作用动力分析程序ＤＩＡＳＳ．文中给出数值算例。本文的工作为对二相饱和土壤介质更深入的研究打下了基础。
Based on the foundational two-phase medium finite element formulations which are given in this paper, the authors put forward a gencral method of considering elastic-plastic effect.The computer program DIASS used for analysis of interaction between soil and structure has been developed. Practical examples are given. The work of this paper lays a foundation for deeper research on nonlinear analysis.
