| 摘 要： | Biot’s theory of consolidation of saturated soil regards the con-solidation process as a coupling problem between stress of elas-tic body and flow of fluid existing in pores.It can moreprecisely reflect the mechanism of consolidation than Terzhi-gi’s theory.In this article,we obtain the general Biot’sfinite element equations of consolidation with classical varia-tional principles.The equations have clear physical meaningand have been applied to analysing the consolidation of Bajia-zui earth dam.The computational results are in accord withengineering practice.
