| This paper summarized several common leakage detection methods in landfill, pointed out the electrical method had become the main method for the leakage detection in different operation stages of landfills (construction period and operation period), and analyzed the applicable conditions, advantages and disadvantages of the electrical detection method in each stage. In the stage of impermeable membrane laying, dual electrode method or electrode dipole method was usually used for construction integrity test. In landfill operation period, electrode grid method, IoT based monitoring and early warning cloud platform, array dipole method or high density electrical method could be applied to membrane leakage detection and long term monitoring according to the actual situation of the site. |
