[Comparison of two types of double-lined simulated landfill leakage detection based on high voltage DC method].
Two types of double high density polyethylene (HDPE) liners landfill that clay or geogrid was added between the two HDPE liners. The general resistance of the second mode is 15% larger than the general resistance of the first mode in the primary HDPE liner detection, and 20% larger than that of the first one in the secondary HDPE liner detection. High voltage DC method can accomplish the leakage detection and location of these two types of landfill and the error of leakage location is less than 10cm when electrode space is 1m.
