摘　　要：基于二维稳定渗流场的基础之上,推导非稳定渗流场的有限元求解格式。编写相应程序计算渗流场各节点水头值,最后运用程序对一简单工程算例进行有限元分析。结果表明,所编写程序符合渗流场一般规律,为进一步对大坝工程进行相关渗流分析奠定了一定的基础。Based on solving two dimensional steady seepage field, the finite element formulation of unsteady seepage field is derived. The corresponding program is developed to compute the node water head in seepage field. Finally the finite element analysis of an engineering case is illustrated. It has been shown that the program keeps consistent with General Law of seepage field and establishes the foundation for more seepage analysis of dam engineering.
