摘要
土壤受到NAPLs污染后其孔隙液成分发生变化,引起土壤电阻率变化,本研究就电阻率法的基本原理以及影响土壤电阻率的主要因素作为切入点,选取粗砂、细砂、粉土、粘土作为本次实验对象,通过室内模拟NAPLs污染土实验,研究了污染土壤电阻率与NAPLs污染物含量之间的变化规律,并分析了含水率和温度对NAPLs污染土电阻率的影响特征。
When NAPLs contaminants invade the soil,the composition of pore fluid and the electrical conductivity of soil will be changed.In this research,considering the basic principles of the resistivity and the main factors affecting the resistivity of soil,the coarse sand,fine sand,silt and clay are selected as the experimental object and through the indoor experimental simulation of contaminated soil by NAPLs,the relationship between the soil resistivity and content of NAPLs contaminants is studied,and also it is analyzed the influence characteristics of the resistivity of contaminated soil by NAPLs when moisture content and temperature changed.
