Paper title: A SIMPLE APPROACH FOR MODELING MULTILAYERED GROUND

Author(s): NENAD CVETKOVIĆ, MIODRAG STOJANOVIĆ, DEJAN JOVANOVIĆ,

Abstract:

In this paper, an optimization procedure for modeling multilayered soil structure, consisting of finite number of horizontal layers, as a homogeneous soil of constant specific conductivity is presented. The equivalent specific conductivity value is determined using anew expression included into procedure. The expression is formed using the Greenís functions for a point source in multilayered media obtained by solving the Poissonís i.e. the Laplaceís equation for electric scalar potential and the method of moments. The approach is applied to the problem of a vertical ground electrode buried in soil structure consisting of three horizontal layers. The electrical parameters of the soil structure and thickness of each layer have been taken from experimental measurements.
