In this study, an experimental research is conducted to determine the influence of field conditions on the soil dielectric constant in order to evaluate the feasibility of using TDR method as a cavity exploration. Dielectric constant of the ground considering field conditions(e.g. casing and ground disturbance) was measured using TDR method. The results conclude that the dielectric constant of ground tended to decrease with the increase in the water contents and density.
