| 摘 要： | 采用有限元法对起伏地形下存在不均匀极化体时的多种地电断面进行了固定点源测深的正演数值模拟计算；提出并实现了在起伏地形下利用固定点源测深法资料作相对强度断面图、确定极化体空间位置的方法；通过对不同条件下数值模拟结果的定量解释计算和分析，证明了该方法的有效性；初步总结出了地形对定量解释结果的影响规律。

| Abstract: | At first, the authors numerically calculate many apparent polarizability sounding curves of various IP ore bodies below undulatory terrain by using the improved 2 dimension finite element program, then present the relative intensity method locating the target on mountainous districts for Fixed Point Source Sounding(FPS).Direct application of the new method to FPS data has achieved many good results which demonstrate the effects of this method. Finally, the authors summarize the rules of terrain influences in this paper. |
