Permeability of soil plays an important role in geotechnical engineering and is commonly determined by methods combining measurements with theory.
Using the double-scale asymptotic expansion method, the Navier-Stokes equation is numerically solved to calculate the permeability, based on the homogenization method and the assumption that the homogeneous microstructure of the relevant porous media is represented accurately as the Representative Elemental Volume (REV).
In this study, the commonly used square model is tested in the calculation of sea clay permeability.
The results show large deviations.
It is suspected that the square model could not represent the flattened shape of the clay particles and the bound water film wrapping around them.
Hence, the Rectangle Particle-Water Film Model (i.e., the R-W model) is proposed.
After determining the horizontal and vertical characteristic length of the unit cell using two pairs of initial data, the permeabilities of other different void ratios could be inversely calculated.
The results of three types of clay obtained using the R-W model agree well with the experimental data.
This shows the efficient feasibility and accuracy of the R-W model by providing a good representation of the clay particles when using the double-scale asymptotic expansion method to calculate clay permeability.
