<p>Studying the physical and thermodynamic properties of contaminated soils is important for restoring ecological vegetation and protecting the environment in contaminated areas. In this study, the resistivity, thermal conductivity, and pore structure of waste cooking oil-contaminated soils in different states were tested with soils containing different water contents (9%, 12%, 15%, 18%, and 21%) and oil contents (0%, 4%, 8%, 12%, 16%, and 20%). The test results showed that the soil water content and resistivity were negatively correlated; the water content was less than the plastic limit, and the resistivity value first decreased and then increased as the water content increased. The water content was greater than the plastic limit, the resistivity value decreased with an increase in the water content, and the rate of decrease declined. The incorporation of oil significantly decreased the value of thermal conductivity; the oil content increased to 12%, the soil was saturated, and the value of its thermal conductivity increased abnormally. The results of this study provided important parameters for engineering problems, such as the remediation of contaminated soil, and may act as a framework for mechanistic explanations of changes in the resistivity and thermal conductivity of contaminated soil.</p> Graphical Abstract <p></p>
