Study on Pollution in Shanghai Contaminated Site Based on Resistivity CPTU

The resistivity of soil is the basic parameter that characterizes the conductivity of soil in contaminated sites. It is very important to evaluate the resistivity of soil in contaminated sites. As normal CPTU’s development, resistivity CPTU (RCPTU) takes both the advantages of CPTU and traditional resistivity method in pollution evaluation. In this paper, RCPTU was used to test the 5 boreholes in the contaminated site of Shanghai Chemical plants and obtain the resistivity values of different depth. Combined with the indoor test data, the relationship between the resistivity of contaminated soil and heavy metal pollution was analyzed. As resistivity is also influenced by porosity ratio, the relationship between relative density and site pollution is also analyzed based on data from RCPTU results.
