Abstract

Singapore government is strongly promoting the development and utilization of underground space in national level due to the nature of the city state which lacks the land. As well as conventional underground utilization in shallow depth such as metro and underground roads, large rock cavern utilization has been started after the successful completion of the underground ammunition depot in the rock, and Jurong Rock Cavern, the second large underground cavern project has just been completed. In this paper, after evaluating the conditions of the underground development in rock mass through the analysis of the geology of Singapore, the history and current status of underground development are examined. Several creative development plans from Singapore government such as underground reservoirs, underground automation logistics systems and underground warehouses storage etc. are introduced with technical issues. This paper also discusses the problems and issues related to the development of large underground space in rock mass in Singapore. It is expected that such active development of underground space in Singapore can give many opportunities and also challenges for rock engineering and industry in the future.

싱가포르는 국토가 부족한 도시 국가의 특성으로 인해 지하 공간의 개발 및 활용을 정부차원에서 전 국가적으로 강력하게 추진하고 있다. 특히 지하철과 지하 도로와 같은 일반 얕은 심도의 지하공간의 활용 뿐 아니라 대규모 지하공간 사업으로서 암반 내 지하 탄약 저장고 프로젝트를 성공적으로 마친 이후, 두 번째 대규모 암반 지하공간 프로젝트인 Jurong Rock Cavern을 얼마전 준공한 바 있다. 본 논문에서는 싱가포르의 지질 분석을 통해 암반 지하공간 개발의 조건에 대해 평가한 후, 싱가포르의 다양한 지하공간 개발의 역사와 현황을 살펴본다. 지하 저수지, 지하 자동화 물류 시스템 및 물류 저장 창고 등 정부 차원에서 향후 추진이 예상되는 창의적인 암반내 주요 지하공간 관련 계획 및 기술적인 이슈들에 대해서 소개한다. 또한 이러한 대규모 암반 지하공간 개발에 관련된 향후 문제와 이슈들에 대해서 논의한다. 싱가포르의 이러한 적극적인 지하공간 개발 움직임은 또한 암반공학 및 업계에 향후 많은 기회와 과제를 줄 것으로 기대된다.
