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.
两种双高密度聚乙烯（HDPE）衬垫垃圾填埋场，即在两层HDPE衬垫之间添加了黏土或土工格栅。在一次HDPE衬垫检测中，第二种模式的总阻力比第一种模式的总阻力大15%，在二次HDPE衬垫检测中比第一种模式大20%。高压直流法可完成这两种类型垃圾填埋场的渗漏检测与定位，当电极间距为1m时，渗漏定位误差小于10cm。
