摘　　要：首先介绍了渗透性评价指标的测定方法.通过对4组试块(24个试样)进行pH值测试、金属元素含量的测定,得出了岩土的pH值小于7,显酸性,对提高抗渗性能作用较大,岩土的金属元素含量对抗渗性能影响不大;又进行了抗渗试验,得出了渗透系数与抗渗标号的关系,氟硅酸钠对抗渗性能影响较大;并进行x射线衍射的成分分析,对岩土的渗透性能进行剖析.The method of measuring the standard of permeability is firstly introduced. And then, through measuring the four specimen' s PH value and metal element content, the results are that PH value of the soil is lower than 7, and is acid, thus it plays an important role in improving the impermeability, but the metal element content has little influence on the impermeability. In addition, through the impermeability experiments, the relationship of permeability coefficient and impermeability grade is established, and sodium fluorosilicate has more influence on the impermeability. Finally, the component of specimens is tested by the X - ray diffraction and the permeability of the soil is studied.
