지하공간건설정보모델링(GeoBIM) 기반의 디지털 트윈 구축사례에 관한 연구

A case study of digital twin construction based on geospatial building information modeling (GeoBIM): Focusing on the case of Jaeamcheon-gul and Jeonggusu-gul in Jeju Island

In the era of the 4th industrial revolution, smart construction is actively researched, in the domestic construction field, and one of the key elements in this field is Building Information Modeling(BIM). In Korea, smart construction is being implemented through BIM-based digitization and intelligence. The geotechnical engineering field should also prepare for the introduction of BIM. In this study, the concept and application status of GeoBIM were identified, and the direction of future research was presented. This study is a part of the study “Establishment of GeoBIM-based Digital Twin Maintenance System” in the current “Technology Development for Establishment of Jeju Ground Collapse Response System for Safe Road Operation”. The subject and scope of the study is continuous excavation at caves located under roads in Jeju Island, and initial research is being conducted on Jaeamcheon-gul and Jeonggusu-gul. This study aims to build a digital twin through individual data construction and integration processes such as cave shape modeling using laser scanners, 3D stratum modeling using borehole information and geophysical exploration data, and modeling of surrounding conditions using drones.
