Forward study of complex resistivity on chromium slag contaminated site model

摘要

The complex resistivity method is used as the detection method to investigate into the chromium concentration of chromium slag contaminated site. Cole-Cole model is confirmed to be used as the model of the relationship between the chromium concentration, water content as well as other soil's physical parameters and the complex resistivity. Before the detection on the actual site, the simulation model on the pollution site should also be setup to verify the accuracy of forward and inverse calculation. The paper focused on forward calculation. Based on the investigation data of the typical chromium slag contaminated site, the forward calculation model was set up. Based on dipole-dipole equipment, the apparent complex resistivity with multiple frequency points was obtained. Thus, this paper analyzed how the site model's physical parameters and Cole-Cole's parameters affected the apparent complex resistivity.
