Description

Geo Resistivity Test Mutil Electrode Electrical Resistivity Imaging System

Electrical Resistivity Imaging System(also named2D ERT) is a non-invasive geophysical method of primary interest for addressing subsurface engineering problems. The method is based on the assumption that subsurface geological materials have significant resistivity contrasts that can be identified based on measurements on the surface. The 2D ERT survey method has been shown to be useful as a cost-effective and rapid method to obtain wide area subsurface information that is relevant for subsurface engineering problems.

The electrical resistivity imaging system is one of the most widely used near-surface geophysical survey methods for civil engineering applications. For identification of bedrock structures cavities or sinkholes geotechnical site investigation slope stability investigation and unknown bridge foundation determination , also The electrical resistivity imaging system may be used for various other purposes in subsurface engineering investigations,Including investigating the subsurface geology of a building construction site, determining the depth of an unknown bridge foundation, and determining seepage from the earthen embankments of a wastewater treatment pond system.
