摘要：Complex resistivity method is used to measure the concentration distribution of chromium salt in the chrome-contaminated 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 ofsoil electrical test show that the soil has not only resistance character, but also capacitance character. TheCole-Cole complex resistance model of rock is used as the complex resistance model of soil. Cole-Colemodel has four parameters: resistivity, time factor, charge rate and frequency factor. The math relationbetween soil physical parameter and measured resistivity is based on the solution resistivity. The mathrelation between soil physical parameter and time factor is derived from the double layer deformation, whichincludes electromagnetic field theory and the double-gel plate model. Finally, the theoretical derivation iscompared with the experimental data to verify its accuracy.
