Abstract

The sea dike is the most important facility of reclamation projects, and plays an important role in securing freshwater in the reservoir. Systematic research on practical approaches and data analysis techniques are lacking even though some geophysical methods such as electrical resistivity and self-potential surveys are included within the inspection processes. Hence, geophysical methods were considered for improvement of precision safety diagnosis methods after problems in the maintenance system have been identified, such as safety checks and precision safety diagnoses. In addition, geophysical methods customized according to variations in ambient environmental limiting factors such as pore pressure changes by tidal fluctuation, compaction characteristics of the fill materials, and the surface condition of the embankment were suggested.

방조제는 간척사업을 위한 중요한 시설물로서 방조제 내측의 담수 확보를 위한 중요한 기능을 담당한다. 정밀안전진단 과정에서는 전기비저항 탐사, 자연전위 탐사 등 지구물리학적 방법들이 일부 반영되고 있지만, 그 중요성에 비하여 적용방법과 획득된 자료의 해석기술에 관한 연구는 미흡한 실정이다. 본 연구에서는 현재 진행되고 있는 육안조사 위주의 방조제 안전점검, 정밀안전진단 등 유지 관리 체계의 문제점을 파악한 후, 정밀안전진단의 조사방법에 대한 개선방안으로 지구물리학적 방법들에 대해 고찰하였다. 한편 주변 환경적 변화에 의한 제한적 요소들(조위변화에 따른 제체의 압력변화, 성토재의 다짐 특성, 제체 표면의 피복상태)을 고려하여 방조제 환경에 따른 맞춤형 지구물리학적 방법들을 제시하였다.
