| 摘 要： | 复杂地形严重地影响可控源音频大地电磁测深(CSAMT)的解释结果,为此,笔者考虑了地形的影响,将地电断面模型经过精细剖分,对模型正演计算的数据进行CSAMT二维反演,得出的结果与正演模型的形态基本一致,获得的电性断面能很好地反映地下地质结构,与实际地质资料相吻合,证实了该方法的正确性和有效性。 |

| Abstract: | Complex topography seriously affects the interpretation of CSAMT. Considering the influence of the topography, the authors analyzed in detail the geoelectric section model and made CSAMT two-dimensional inversion for the direct calculation data of the model. The result is basically consistent with the shape of the direct model. The electric section obtained can satisfactorily reflect the underground geological structure and accord with the geological data. All this proves the correctness and effectiveness of this technique. |
| Keywords: | controllable source audio frequency magnetotelluric method influence of topography two-dimensional inversion Occam inversion |
