用有限单元法模拟各向异性介质中二维电性异常体的大地电磁响应
Modelling of Magnetotelluric Responses of 2-D Electrical Anomalous Body in Anisotropic Media Using Finite Element Method
摘要
Abstract
The variations of 2-D MT field in anisotropic medium for conductivity were studied in this paper.The electromagnetic field was worked out with finite element method (FEM),and the apparent resistivity was obtained with the help of auxiliary field after variational problems in an anisotropic medium were solved.The differences of magnetotelluric field between anisotropic and isotropic media under TEz mode were discussed.Furthermore,the influence of dipping anisotropy and varying frequency was analyzed on the change of MT field.Finally,the characteristics of MT field response in the anisotropic media were obtained after discussing the effects of high resistance and low resistance on MT field and the impact of resistivity parallel to and perpendicular to the strike of structure.关键词
