Abstract

Recently, the 3D image of the geotechnical information has been constructed along with the 3D integrated underground space mapping project. Prior to the visualization of the 3D image of the geotechnical information, it is necessary to analyze and verify the accuracy of the geotechnical information. Previous studies evaluated the precision of collected geotechnical information DB to validate the quality of the collected DB and later studies on the 3D precision were performed to provide the basic data for the 3D integrated underground space map. In this study, practical application methodologies are suggested based on the previous studies to improve the accuracy of the applied geotechnical information and further to improve the reliability of the constructed 3D integrated underground space map.

최근 3차원 지하공간통합지도 구축 사업과 더불어 지반정보를 3차원으로 가시화하는 연구가 진행 중에 있다. 이러한 지반정보의 3차원 가시화를 위해서는 우선적으로 지반정보의 정밀도를 분석하여 검증 할 필요가 있다. 2013～2014년은 수집 DB에 대한 정밀도를 검증하는 연구가 진행되었으며, 최근 지반정보의 3차원 구축을 위한 기초자료 제시의 일환으로 지반정보의 정밀도를 분석하는 연구가 진행되었다. 이러한 연구들에서 더 나아가 본 연구에서는 시추정보의 정밀도 향상 방안 및 지층 모델링을 위한 지반정보의 활용 방안을 제시하여 신뢰성 있는 3차원 지반정보의 구축 방안을 제시하고자한다.
