Abstract:

 In this study, we have conducted experimental research on different types of landfill including construction and household waste in a city of Hebei province by using various geophysical methods, such as highdensity resistivity method, groundpenetrating radar method, highprecision magnetic measurement method, induced polarization method and the transient electromagnetic method. According to the measured data and combined with the geological and geotechnical characteristics of the working area, we point out the role and the capacity of different geophysics methods in delineating and monitoring the coverage and spreading trends of the pollution of a landfill. It has been found that the ground penetrating radar method, high density resistivity method, induced polarization method and transient electromagnetic method have some effects in detecting contamination leakage of a landfill. The experimental research shows that besides the high density  resistivity method, the induced polarization method also has a good effect in monitoring the scope and trend of pollution and delineating the degree of contamination.
