考虑到可变形多孔介质的渗透系数依赖于孔隙变形的特点，建立了一维孔隙压力生成的力学模型，用初始层校正法来出了摄动解，实例计算了表明渗流的非线性对孔隙压力分布菜明显影响，最后介绍了利用孔隙压力生成过程中，流出试样的非稳定流量确定可变形多孔介质渗透系数的方法，测试时间大大小于传统的稳定渗流方法。

The Formation of the One-Dimensional Pore Pressure in Deformable Porous Media

Accounting for the characters that the permeabilities of deformable porous media vary with its deformation, the machamical model for forming one-dimensional pore pressure is established. The asymptotic solution is obtained by applying initial layer correcting method; The case calculation indicates that the nonlinearity of the flow has an important role in the distribution of pore pressure. Finally, a method for determining the permeability of deformable porous media according to the unstable discharge of fluid from the top end of specimen is introduced, the method takes much less period of measuring time than traditional laboratory method.
