Abstract

Two-dimensional electrical resistivity surveys have difficulty in identifying the electrical resistivity distribution at both ends of the survey line due to insufficient data coverage. To overcome this limitation, the length of the survey line must be extended. However, depending on the field situation, it is often not permitted to extend the survey line. This study proposes a method to effectively image the electrical resistivity at both ends of the survey line by combining surface and borehole surveys to overcome this problem. The effectiveness of the proposed method was analyzed through numerical experiments, and its applicability was examined through inversion of field data.

2차원 전기비저항 탐사는 가탐 영역의 한계로 측선 양단의 전기비저항 분포를 파악하기 어렵다. 이러한 한계를 극복하기 위해서는 측선의 길이를 연장해야 하지만, 현장 여건상 측선 연장이 불가능한 경우가 빈번하다. 이 연구에서는 이러한 문제점을 극복하기 위하여 지표 탐사와 시추공 탐사를 병행하는 방법을 통하여 효과적으로 측선 양단 하부의 전기비저항 영상화 방법을 제시하였다. 수치실험을 통하여 제시된 방법의 효과를 분석하였으며, 현장 자료의 역산을 통하여 그 적용성을 검토하였다.
