Abstract

In order to improve the productivity in the civil engineering field, efforts to apply BIM have been continuing, however, research on information modeling of tunnel structures considering alignment is insufficient. In this study, we proposed the method of building tunnel models reflecting curved alignment by transferring point data to BIM Authoring Tools(BAT) through discretization of alignment in Alignment-centered Modeling Tools(AMT). IFC data schema was derived to consider the physical and spatial elements of tunnel structures and alignment and IFC-based information management for tunnel alignment, tunnel structures and ground conditions was possible by referring to the extended data schema and including meanings in IFC property sets. The ratings for ground condition in Rock Mass Rating(RMR) and Q-system was automatically derived by using generated information model according to the proposed method.

토목분야 생산성 향상을 위해 BIM을 적용하기 위한 노력이 계속되고 있으나, 선형과 지반에 대한 정보가 필수적인 터널 구조물의 정보모델링에 대한 연구는 미흡한 상황이다. AMT에서 생성된 선형의 이산화를 통해 포인트의 정보를 BAT로 전 달하여 곡선 선형을 반영한 터널 모델 생성 방안을 제시하였다. 철도 구조물과 선형에 대한 물리적 요소와 공간적 요소를 모 두 고려할 수 있도록 IFC 데이터 스키마를 확장하였으며, 확장된 데이터 스키마를 참조하여 선형, 구조물, 지반 정보에 대한 의미정보를 PSET에 담아 IFC기반의 정보관리를 가능하게 하였다. 제안한 방법에 따라 생성한 정보모델을 통해 터널과 밀 접한 암반 등급을 자동으로 도출함으로써 활용성을 검증하였다.
