【Abstract】 The Boundary Element Method(BEM) is a new method of numerical calculation of differential equation. In this paper, the basic principle and processing technology solving potential field problems of the 2—D geoelectrical bodies with topographic effects in the point source field are discussed. The results of calculating apparent resistivities and polarizabilities for different geoelectrical bodies and applied examples are also given. The results show that BEM is an economical and efficient numerical method to solve boundary-value problems and to process data of electrical prospecting.更多还原
