Application of Electromagnetic Geophysics (EMG) Technology to Subsurface Investigations

摘要

Electromagnetic geophysics (EMG) consists of several emerging, non-destructive, wave propogation technologies that have the potential to minimize the number of required soil borings and associated costs, by providing reliable indirect information about subsurface conditions. Currently, some methods of EMG used to assess subsurface soil conditions and characteristics are, because of their complexity and specialized character, viewed as something of a black box technology. The objective of this project was to analyze several of the various EMG methods, capabilities, applications and limitations, and issue guidelines for possible WisDOT use of EMG in site characterizations. Research tasks included assessment of current practice, literature search, contractor data collection, and collection of data on equipment, cost and training.
