摘要
土壤介质被渗滤液污染后,其电学性质发生变化,可为电法探测介质的污染范围、程度及扩散动态提供地球物理探查基础。通过构建土壤污染介质模型条件,采用并行电法探测技术进行探查模拟试验,进一步分析污染介质的电性反应及其特征。试验结果表明,污染土壤导电性差异增大,电阻率测试方法可有效判识其影响范围及特征,为地下介质污染评价提供技术支撑。
The electrical property of the soil medium will change after the soil is polluted by landfill leachate, which provides the theoretical basis of geophysics tests for forecasting the pollution scope, degree and diffusion characteristics of landfill by means of the electrical method. In the article, the pollution process of leachate leak- age is imitated by establishing the physical model. The experiment simulation work is carried out with the parallel electrical method, and the electrical reaction and its characteristics of pollution medium are analyzed further. Ac- cording to the testing results, the electrical conductivity difference of pollution soil is enlarged, and the changing scope and characteristics of the pollution can be decided through the resistivity test method. The parallel electri- cal technology can provide the technical support for the pollution assessment of underground medium.
