Abstract

In this study, a tunnel information database system was developed to optimize the process of assessing and analyzing geological information from the life cycle of tunnel construction. All data from every stage in tunnel construction can be put into the system and be utilized for the decision making. In the system, tunnel face mapping information can be managed by digital format which can be easily transformed into 3D visualization module and thus help analyzing geological discontinuities. The system was applied to waterway and road tunnel in domestic area to verify its effectiveness.

본 연구에서는 터널의 시공 중 굴착면을 통해 획득되어지는 지질정보의 분석과 평가의 객관화를 위해 디지털 매핑 데이터베이스 시스템을 개발하였다. 지질조사 정보와 설계단계에서의 다양한 정보를 데이터베이스화 하고 이를 시공 중 조회하여 활용할 수 있도록 하였다. 시공 중에 굴착면의 평가를 디지털 이미지 기반으로 관리할 수 있도록 하였다. 또한, 3차원 가시화 모듈을 통해 불연속면 정보 등의 분석 및 평가에 활용 할 수 있도록 하였다. 개발된 시스템은 실제 시공 중인 수로 터널 및 고속도로 터널 현장에 적용함으로써 효용성을 확인하였다.
