摘要 Using the Green’s theorem, the boundary value problem of point source electric field under the circumstances of three-dimensional topography and homo-anisotropic rock is converted into boundary integral equation.Afterward, the ground surface is divided into triangular elemenis and the integral equation is converted into linear algebric eq u ations ystem by using Gauss quadrature rule. Solving the equation System,we can obtion the values of electric potential on the surface~ The numerical method proposed in this paper can be performed bysmall even microcomputer.
