31 de oct. de 2006 · A former dolerite quarry and landfill site was investigated using 2D and 3D electrical resistivity tomography (ERT), with the aims of determining buried quarry geometry, mapping bedrock contamination arising from the landfill, and characterizing site geology. ... while the fault zone appeared in the 2D resistivity model as a dipping structure ...
electrical resistivity method to detect faults and Figure 1 N–S oriented geological cross-section of the Tournemire plateau. The experimental platform is located in the central part of the tunnel Vol. 167, (2010) Potential of Electrical Resistivity Tomography to Detect Fault Zones 1407
29 de may. de 2015 · In this study, we assessed the potential of Electrical Resistivity tomography surveys to image fault and fractured zones in the Experimental Platform of Tournemire. We first compare ERT images acquired with the Wenner configuration and electrode spacing ranging from 2 to 40-m.
28 de mar. de 2024 · Electrical resistivity methods measure the ability of electrical current to flow through the subsurface. Thus, resistivity methods require electrical connection (i.e., galvanic coupling) with the ground, and this is achieved with the use of metal electrodes. Typically, a battery-run power supply is used to apply a direct current (DC) between ...
27 de feb. de 2022 · Fractures greatly impact the hydraulic and mechanical characteristics of fault zones; thus, the hydraulic characteristics of single fractures are critical for better understanding the hydrology of regional fault zones. A number of geophysical methods are applicable on the in situ field measurement scale. Electrical resistivity tomography (ERT) is a sensitive and nondestructive approach capable ...
1 de sept. de 2009 · Electrical resistivity tomography (ERT), which can have an effective depth of investigation of several hundred meters, has been applied to the detection of buried faults in urban areas on the China mainland since 2001, and has proven to be one of the most powerful geophysical tools for this application.
1 de sept. de 2011 · The use of an integrated electrical resistivity tomography and self-potential survey permits us to highlight some fractured zones ...
