摘要
不同含水率、不同铬污染物浓度土壤的复电阻率频散实验,是复电阻率探测方法评价铬渣污染场地的物理基础。实验研究发现,土壤含水率和污染物浓度的不同均会对复电阻率幅值、复电阻率相角、同相电阻率和异相电阻率的测量结果产生影响,但是异相电阻率和相角具有明显的频散特性。研究结果表明,利用基于土壤频散特性发展起来的复电阻率探测技术,可快速有效地对铬渣污染场地进行评价。
The complex resistivity dispersion experiment on soils with different water and chromic salt proportions constitutes the basis of the complex resistivity detection method used to evaluate the field polluted by chromium residue.Based on experiments on the soil complex resistivity dispersion properties under various kinds of conditions,the authors have found that the complex resistivity amplitude,phase,in-phase resistivity and out-phase resistivity can be influenced by the water content and contamination content,but the complex phase and out-phase resistivity and the phase angle have obvious dispersion properties.The experiment results show that the complex resistivity detection technology based on soil dispersion properties can be used to evaluate the field polluted by chromium residue rapidly and effectively.
