| 摘 要： | 本文实现了非平坦地形条件下电阻率三维反演，讨论了几种消除反演中地形影响的方法. 结果表明，只有将地形直接带入反演算法中，进行带地形电阻率三维反演才能有效消除地形影响及其对反演结果的偏差，得到与地下电性结构相符的反演结果.

| Abstract: | 3-D resistivity inversions under the condition of uneven terrain are presented in this study, and several methods for erasing topographic influence in the inversion are discussed. It is shown that only the inversion incorporating topography, in which the topography is directly incorporated into the inversion algorithm, can effectively erase the topographic influence and correct the error in inversion result, obtaining the inverted model in agreement with subsurface geoelectrical structure. |
