Resistivity Surveying For Planning Of Infrastructure

Resistivity surveying can play an important role for providing a geotechnical planning basis<br>for infrastructure projects if used in an early stage of the pre-investigations. The result can<br>then guide the selection of geotechnical drilling and sounding points, to ensure that the<br>selected points are representative. It can also decrease the total number of drilling points<br>needed. In order to be an attractive method which complements the traditional geotechnical<br>methods resistivity surveying has to give an area1 cover, be economically efficient and provide<br>easily accessible presentations. This in turn makes it necessary to automate data collection,<br>interpretation and presentation as far as possible, and an approach for this is presented<br>together with results from two field sites.
