Advanced computation of the field apparent resistivity of the soil for driven-rod electrodes
Abstract
In this paper, analytical formulas for the computation of the field apparent resistivity of the soil for driven-rod electrodes are presented. General four driven-rod electrode array configuration and its special cases: general symmetric, Schlumberger and Wenner driven-rod electrode array configurations are considered. For the Wenner four driven-rod electrode array configuration, the percent deviation of the field apparent resistivity computed by a formula valid for point electrodes was investigated. The exact values of the measuring instrument reading are computed by software package UZEM for chosen homogeneous soil as well as radii and burial depths of the four driven-rod electrodes. On the basis of computed discrete values of correction functions for the Wenner four driven-rod array configurations, correction functions are obtained. These correction functions are valid only for chosen radii and burial depths of driven-rod electrodes.
