이방성 층상구조에 대한 전위와 전기장 및 전기비저항탐사 계산 연구 = Forward Calculation of Electric Potential, Electric Field and Resistivity Survey on Anisotropic Layered Half Space

다국어 초록 (Multilingual Abstract)

We followed and extended the algorithm originally made by Das (1995) to calculate the electric potential and field induced by electric current in arbitrary anisotropic layered structure. We confirmed all the theoretical contents and coded the corresponding program to acquire the electric potential and field. Further we extended to forward estimation of apparent resistivity to be attained by electrical resistivity survey on anisotropic layered structure with differing the electrode spacing and azimuth of anisotropy. The effects of anisotropy were reviewed by considering some examples.
