Abstract

Due to recent underground space accidents, are a frequent occurence in Korea, the government established the basic plan for the construction of the IUGIM (Integrated Underground Geospatial Information Map) in 2015 as a measure for safety management of underground spaces. The development of IUGIM was partially completed as of 2021. The underground space management entity and related organizations are utilizing it. This study is being carried out as part of a plan to improve the usability of IUGIM, and to build a visualization system that compares real-time field data with stored data. A system, equipped with a visualization function for borehole data and 6 types of underground facilities built and managed on IUGIM; a tool capable of comparative analysis with real-time data measured in the field, is being built. The 6 types of underground facilities are water supply pipe, sewage pipe, power pipe, gas pipe, communication pipe, and heating pipe. The completed system was demonstrated at three locations in Seocho-gu, Gangnam-gu in Seoul. The field demonstration was carried out by accessing the mobile center and downloading IUGIM data, visualizing IUGIM data (surface creation, borehole information, underground facilities), and visualizing the GPR(Ground Penetrating Radar)-based data acquired at the field. As a result of the empirical results of IUGIM data and GPR-based field data, it was judged to be suitable. As a result of this study, it is judged that it can be helpful for safe construction at the excavation site.

최근 국내에서 빈번하게 발생하는 지하공간 사고에 기인하여 정부에서는 지하공간 안전관리 대책으로 지하공간통합지도(IUGIM: Integrated Underground Geospatial Information Map) 구축의 기본 계획을 2015년에 수립하여 2021년 현재 부분 구축이 완료된 상태이고, 지하공간 관리 주체 및 관계 기관 등이 활용 중이다. 본 연구는 지하공간통합지도의 활용성 향상 방안의 일환으로 수행 중이며, 현장에서 계측된 실시간 기반의 데이터와 지하공간통합지도 내에 저장되어 운용 중인 보관 데이터의 비교 작업을 수행하기 위한 가시화시스템을 구축하는 내용을 다룬다. 지하공간통합지도에 구축되어 관리되고 있는 시추공 데이터 및 지하시설물 6종에 대한 가시화 기능을 탑재한 시스템을 구축하였다. 지하시설물 6종은 상수도관, 하수도관, 전력관, 가스관, 통신관 및 난방관이다. 구축 완료된 시스템은 서울시 강남구, 서초구 일원 3지점에 대한 현장 실증을 수행하였다. 현장 실증은 모바일센터에 접속해서 지하공간통합지도 데이터 내려받기, 지하공간통합지도 데이터(지표면 생성, 시추정보, 지하시설물) 가시화 작업, 현장에서 취득한 GPR(Ground Penetrating Radar) 기반 데이터에 대한 가시화 등으로 진행하였다. 지하공간통합지도 데이터 및 GPR 기반 현장 데이터의 실증 결과 적합한 것으로 판정되었다. 본 연구의 결과로 굴착 현장에서 안전한 시공에 도움이 될 수 있을 것으로 판단된다.
