摘要

Based on Biot consolidation theory and pore water continuity principle, differential equation groups and boundary conditions for seepage field and stress field were established respectively. By using Galerkin variation theory and eight-node isoparametric element, differential equations were discretized in terms of both space and time, the coupled finite element equations of seepage field and stress field were established and the solution of the coupled finite element equations was introduced. An example was given to show the effect of seepage in this coupled model. The coupled model analysis can present some base for theoretic research in fluid-solid coupling analysis and reference value for prevention and cure in slope engineering.
