A SIMPLIFIED PROCEDURE FOR APPROXIMATE DETERMINATION OF ELECTRO-GEOMETRICAL PARAMETERS OF TWO-LAYER SOIL

Determination of electro-geometrical parameters of two-layered soil represents a demanding task, which has been addressed by various techniques over the history. Development of personal computers (PCs) and the reduction of their price, provide application of numerical techniques and procedures for determining those parameters instead of the earlier graphic techniques. One such numerical procedure is described in detail in the International Standard IEEE STD 81-1983. According to the numerical procedure described in the mentioned standard, the parameters of two- layered soil can be determined with high accuracy. However, in some cases when high accuracy in determination of the parameters of two-layered soil is not required, simple algorithms and procedures which are well suited for use in mathematical and engineering simulation software packages of general purpose like Mathematica, MathCAD or MATLAB can be very acceptable, too. In this article one such numerical algorithm is described in detail. The presented numerical procedure is very simple, appropriate for use in general-purpose mathematical and engineering simulation software and is easily applicable in estimating electro-geometrical parameters of two- layered soil.
