摘要：
Expressions for the resistance to earth of earthing grids buried in uniform, two- and three-layer soils are proposed based upon the examination of a large set of grids and soil structures using the finite-element approach. Simple empirical correction factors are introduced to modify the earth resistance formulae for uniform soil to account for the multi-layer soil structure. A comparative analysis of available expressions for uniform and two-layer soils is performed in order to check their applicability in various cases.
