| 摘 要： | 偶极－偶极剖面方法是一种非常流行的物探方法，但就地形对该方法的实质性影响及修正研究得比较少.我们就几种典型的地形畸变情况进行了正演计算，并绘制了拟断面图.通过对这些图形分析，可以看到在地形畸变处的拟断面图不能反映地下地质体的情况，且有效拟断面图是不连续的，需要分段处理，分级解释.

| Abstract: | The dipole-dipole section method is a common geophysical exploration tool in the field. But there is little report about the effect correction of topography aberration on the pseudo-section diagram. We use some typical models to make forward calculation for the apparent resistivity and draw the pseudo-section diagram accordingly. The pseudo-section is seriously distorted from the original one at the topography aberration position. And the effecive pseudo-section is not continuous. We should process the section by splitting it to some segments, and analyze it by grades. |
