| Abstract: | The variations of soil permeability under the process of one-dimension solidity were studied. Based on the statistical analysis on the experimental data, the relationship between permeability, k and soil porosity, e was derived, and its accuracy was analyzed. This relationship provides a reference basis for hydraulic constructions and designs. |
