| 摘 要： | 采用变积方法，建立了一组等温准静态下饱和多孔介质的六类变量的广义变分原理，在此基础上，引入约束条件得到五类变量，四类变量，三类变量和二类变量的变分原理，为建立饱和多孔介质的有限元模型提供了基础。 |

| Abstract: | The generalized variational principles for isothermal quasi static saturated porous media are established by using variational integral method introduced in . Then, by introducing constraints, several variational principles are worked out, including five field variables, four field variables, three field variables and two field variables formulations. |
