Abstract

This study aims to design a tunnel part model for underpass and subway lines that correspond to tunnel sector among the underground facilities(structure types) covered in the integrated map of underground spaces. For this purpose, we compared and reviewed the characteristics of international standards related to tunnel data models. As a result, it was found that CityGML 3.0 - Tunnel module was the most suitable for designing a 3D tunnel data model. Afterwards we reviewed the legal and institutional regulations to derive the standard elements of the 3D tunnel data model. Then we conducted a demand survey targeting experts in related fields to derive standard elements for addition and extension of underpasses and subway lines. Based on the above process, we designed and presented a 3D tunnel data model using UML. This study is expected to be meaningful as a basic study to improve the utilization of tunnel model in the integrated map of underground spaces.

본 연구는 지하공간통합지도에서 다루고 있는 지하시설물(구조물형) 중 터널 부문에 해당하는 지하차도, 지하철 선로를 대상으로 3차원 터널 데이터 모델을 설계하는 것을 목적으로 한다. 이를 위하여 우선 터널 데이터 모델과 관련한 국제 표준 간의 특징을 비교·검토하였으며, 그 결과 CityGML 3.0 - tunnel module이 기존 표준과 비교했을 때 3차원 터널 데이터 모델을 설계함에 있어서 가장 적합한 데이터 모델임을 알 수 있었다. 이후 3차원 터널 데이터 모델의 표준 요소 도출을 위하여 법·제도적 규정을 검토하고, 관련 분야 전문가를 대상으로 수요조사를 실시하여 지하차도와 지하철 선로의 추가·확장 표준 요소를 도출하였다. 위와 같은 과정을 토대로 UML을 이용하여 3차원 터널 데이터 모델을 설계 및 제시하였다. 본 연구는 지하공간통합지도의 활용도 제고를 위한 기반 연구로써 그 의의가 있을 것으로 판단된다.
