摘要
考虑了多孔介质渗透率随孔隙变化的特点，建立了基本方程；对于广义平面应力条件下的径向渗流问题，提出了解耦方法，并求出了耦合条件下的孔隙压力及介质应力、应变、位移的解析解。实例计算表明。
Taking into account the behavior that the permeability of deformable porous media varies with their porosity,the liquid solid problem of liquid flowing through porous media under general plain stress condition is discussed.First the goveming equations are published,then a decoupled method is proposed,and the fields of pore pressure,the stresses,strains and displacement of media are derived analytically.The computation of cases indicates that there are obviously difference between the coupled analysis and non coupled analysis.
