| 英文摘要 | The anisotropy of the earth's internal medium has a great influence on the geophysical exploration. Therefore, it is important to study the responses of magnetotelluric (MT) method in anisotropic media. The boundary conditions play an important role in the accuracy of electromagnetic modeling. The first type boundary condition requires the bottom boundary to be set far enough away from the anomalies, which leads to a larger computational domain and longer computational time. The third type boundary condition has smaller computational scale and higher computational accuracy than the first type boundary condition, which is widely used in the modeling of 3D isotropic media. However, the theory of the third type boundary condition is more complex in anisotropic media. At present, there are no published papers that achieved 3D MT modeling with the third type boundary condition in general anisotropic media. In this paper, for 3D vector finite element the third type boundary condition of the bottom interface in anisotropic media is derived. The reliability and accuracy of the algorithm are verified by several models. The results show that the computational domain with the third type boundary condition can be smaller when the accuracy is the same; and the third type boundary condition has a higher accuracy when the bottom boundary is closer to the anomaly. |
