DC-resistivity mapping of internal landfill structures: two pre-excavation surveys

摘要: Geophysical investigations using 2-D DC resistivity were carried out on old parts of two similar landfills, with waste different ages. The data sets, which included high density in both vertical and horizontal directions, interpreted smoothness constrained inversion. landfills excavated after the surveying. objective was to test capability method as a pre-characterization technique. objectives only partially fulfilled. First, moisture content parameter that appeared exert dominant control over distribution landfill. most important potential information can be recovered is, therefore, an indication piles hydraulics. Second, it neither possible estimate amount recoverable soils, nor correlate type models. However, discrete anomalies identified, if specific materials are searched for, models indicate places search.
