Analysis of Foundation Grounding System Buried in a Horizontal Multilayer Soil by means of Fictitious Conductivity Concept

摘要

The analysis of foundation grounding systems buried in a horizontal multilayer soil is presented by means of fictitious conductivity concept. The calculation can be simplified as grounding systems in a multilayer soil with equivalent current sources added on foundation surfaces. Therefore existed codes based on the moment method can be combined easily. Numerical examples show the effectiveness of proposed approach.
