摘　　要：根据Biot固结理论和孔隙水连续性原理,分别建立了应力场和渗流场耦合模型微分方程组及边界条件,并对耦合微分方程组进行空间离散和时间离散,建立了两场的耦合有限元方程。其研究成果,可为今后的研究工作提供一定的基础,对边坡工程的预防和防治具有一定的参考价值。According to Biot抯 consolidation theory and pore water continuous principle, the basic seepage field抯 and stress field抯 finite element equations and boundary condition are established respectively. By Galerkin theory and pore water pressure, differential coefficient equations are discrelc distributed on space and time domains, then the coupling finite element equations of the seepage field and stress field are established. The conclusions can be of some base for further research and reference value for prevention and cure on slope engineering.
