摘要
以往的研究认为,黄土地层的导水性以裂隙孔洞为主。本文在多种试验数据的基础上,分析了裂隙、孔洞及孔隙对洛川塬黄土地层渗透系数的影响,发现裂隙、孔洞的影响是微弱的,而孔隙的影响是十分强烈的。得出结论认为黄土地层的导水性不是以裂隙、孔洞为主,而是以孔隙为主。
Up to the present, the opinion is that the water conductivity of loess soils comes from fissures and holes. On the basis of a lot of testing data, the author analyzed the effect of fissures, holes and porosity on the coefficient of permeability of Lochuanyuan loess soils. It is discovered that the effects of fissures and holes are weak, and those of porosity very strong. The conclusion is drawn that the water conductivity of loess soils does not come from fissures and holes, it comes chiefly from porosity.
