摘要：
Electrical resistivity method has been used in recent years for evaluating of contaminated soils. Based on laboratory measurement, the electrical resistivity properties such as average formation factor, average shape factor of heavy metal contaminated soils were calculated and analyzed. The relationships between these three electrical resistivity related parameters and water content, porosity, type and contaminated component concentration were discussed. Results showed that the electrical resistivity, average formation factor and average shape factor decrease with the increase of water content, while the more serious the soils are polluted, the lower electrical resistivity, the higher the average formation factor and average shape factor are achieved. These test results may provide a guideline for detecting heavy metal contaminated soils by the electrical resistivity method.
