摘 要: 给出基于混合物理论的流体饱和两相多孔介质模型 ,该模型由一可变形固体相和一流体相组成。采用 Galerkin加权残值法导出求解拟静态问题的有限元公式 ,并编制了二维有限元程序。用程序分析了一维和二维问题 ,得到合理的结果。 Based on the fluid saturated two phase porous media model, which is constituted with a deformable solid phase and a fluid phase, deduced from mixture theory, a finite element formulation for quasi static analysis is given out. Rational results of one dimensional and two dimensional numerical examples, analyzed with the developed program PMFEMS, are obtained.
