Abstract
In order to examine the effectiveness of resistivity measurements for inferring the internal conditions of landfills, we carried out a scale experiment. The container that we used for the experiment was 1.8m long, 1m wide and 0.5m deep. Its bottom was divided into 9 cells with 2 drainpipes. The fill was composed of gravel, incinerator ash and sand in ascending order. 17 electrodes were buried in the ground surface at 10cm intervals along a resistivity profile line. The fill was periodically sprinkled with water. Resistivity measurements were carried out by the dipole-dipole method and the quantities and qualities of leachate from each cell were measured. As a result, an inverse correlation between the electrical conductivity of the leachate and the resistivity of fill was found. A zone identified as having a high resistivity ratio was located above a cell with large drainage volume. In addition, the above results were compared with field monitoring data from an actual landfill.
