| Abstract: | This paper has sifted the parameters for the various key elements of the Luochuan's loess porosity by means of progression analysis.Then,it selected a porosity element which would influence the coefficient of permeability.It also set up a stochastic mathematical model and quantitatively solved a question on the amount and the form of holes which influence the coefficient of permeability.Finally,it preliminarily ascertained the relationship between the permeability and the porosity of the Luo-chan's loess layer. |
