للكاتين E. A. Eisawy and H. A. Sallam Operational Safety Dept., National Center for nuclear safety ABSTRACT Determination of effective earth resistivity for use in deep ground rod resistance calculations is an important contribution to ground design. An Artificial Neural Network (ANN) algorithm for predicting the resistance of deep driven ground rods has been developed. The ANN has been trained …

للكاتبين E.A. Eisawy and H. A. Sallam Operational Safety Dept., National Center for nuclear safety ABSTRACT One major factor in the design of earth electrodes is the soil resistivity. This paper is based on experience obtained at sites with high soil resistivity variations. Many test measurements have been made to study the effect of horizontal variations in soil resistivity at …
