The Application and Research on the Dual-fequency IP Multi-parameter Interpretation in the Environmental Assessment of Landfill

摘要

Since the leak of MSW(Municipal solid waste) has had a serious impact on human daily living and ecological environment,to effectively evaluate the landfill leakage and its pollution extent,People often apply the apparent resistivity s ρs and the apparent polarizability s ηs (or apparent frequency Fs ) parameters to explain the induced polarization(IP) anomaly.When the IP anomaly is too complicated to use these parameters to reasonably interpret the nature of the anomaly source,it's also possible to infer the wrong conclusions.In this paper,the wavelet approach and the metal factor method have been adopted to explain complex induced polarization anomaly in the environmental assessment of the landfill and solved the jamming exceptions,extracted effective anomalies and distinguished the anomaly of the target al.So,multi-parameter interpretation has directive significance to geophysical applications in the engineering environment.
