Complex resistivity method is used to measure the concentration distribution of chromium salt in the chromecontaminated sites. Both, the salt concentration and moisture content could affect the measurement results, so a theoretical model is needed to distinguish the salt concentration and moisture content. The results of soil electrical test show that the soil has not only resistance character, but also capacitance character. The Cole-Cole complex resistance model of rock is used as the complex resistance model of soil. Cole-Cole model has four parameters: resistivity, time factor, charge rate and frequency factor. The math relation between soil physical parameter and measured resistivity is based on the solution resistivity. The math relation between soil physical parameter and time factor is derived from the double layer deformation, which includes electromagnetic field theory and the double-gel plate model. Finally, the theoretical derivation is compared with the experimental data to verify its accuracy.

Abstract


Complex resistivity method is used to measure the concentration distribution of chromium salt in the chromecontaminated sites. Both, the salt concentration and moisture content could affect the measurement results, so a theoretical model is needed to distinguish the salt concentration and moisture content. The results of soil electrical test show that the soil has not only resistance character, but also capacitance character. The Cole-Cole complex resistance model of rock is used as the complex resistance model of soil. Cole-Cole model has four parameters: resistivity, time factor, charge rate and frequency factor. The math relation between soil physical parameter and measured resistivity is based on the solution resistivity. The math relation between soil physical parameter and time factor is derived from the double layer deformation, which includes electromagnetic field theory and the double-gel plate model. Finally, the theoretical derivation is compared with the experimental data to verify its accuracy.
