Abstract

Approximately 70% of the Korean peninsula is composed of mountains, around 99,274 $km^2$. Even worse, population rate of Korea is the No.3 in the world now. Accordingly, it is necessary to develop the potential underground space actively with the concept of another territory to be utilized. The development of underground space should be considered not a choice but an indispensable issue. Since 1970s, many large-scale underground structures have been constructed like as crude-oil storage bins, liquefied petroleum gas storage caverns, and underground pumped storage powerplants. Also, In urban area, the underground facilities such as subway networks, underground shopping mall, underground pedestrian network, electric power tunnels, and car parking lots have been used extensively. The scale of Yeosu oil and gas underground storage facility and Seoul subway systems are one of the massive scale in the world. Recently, the trend of the development of underground space becomes more diverse and larger scale. The current status of Korean underground space developments and strategy are described in this paper.

우리나라는 99,274 $km^2$의 협소한 면적에 산지가 약 70%을 차지하고 있다. 게다가 인구밀도는 세계 3위의 조밀한 국가이다. 따라서 우리나라는 지하공간을 새로이 활용해야 할 국토로 간주하고 적극적으로 개발할 필요가 있다. 우리에게는 지하공간개발이 선택이 아니라 필수이다. 국내에서는 1970년 이후로 가스 원유비축기지, 지하 양수발전소가 건설되었고 주로 대도시에서 지하철, 상가, 보도, 공동구, 주차장 등의 형태로 지하공간이 활용되어 왔다. 여수 지하석유 비축기지와 지하철은 세계적인 규모이다. 최근에는 지하공간의 개발이 더욱 다양화 되고 또한 대규모화 되고 있는 추세이다. 국내 지하공간 개발현황과 문제점 및 대책에 대하여 소개하였다.
