摘要
本文用逐步回归分析方法对洛川黄土孔隙性诸要素进行了变量筛选,选出了影响渗透系数的孔隙要素,并建立了随机数学模型,定量解决了影响渗透系数的孔隙多少和孔隙形状问题,初步确定出了洛川黄土地层透水性与孔隙性的关系。
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.
