The frequency of flooding is increasing due to heavy rainfall caused by climate change and urbanization. In order to prevent flood damage in low-lying areas, systematic measures are needed for urban watersheds. The underground infrastructure of Shinwol was built to sustained heavy rains that occur more than once every 30 years, which has prevent flooding in the area. Additional construction of underground infrastructure facilities is planned in various areas including Seoul and Busan. Overseas countries have installed numerous underground infrastructure facilities for the purpose of preventing flood damage and improving water quality in urban areas, and have verified their social and economic effects. However, since there are still few cases of introduction in Korea, additional research is needed in various fields such as design, construction, operation, and management. In addition, in order to secure the feasibility and economic feasibility of the business, a multipurpose utilization plan must be developed to enhance the value of water resources and underground infrastructure facilities. In order to maximize the flood prevention effect, which is the original purpose, systematic and stable design and operation technology must be secured. The Ministry of Environment was promoted the ‘Technology development for optimizing planning, operation, and maintenance of urban flood control facilities’ project starting in 2024 to secure core technologies for Korea’s customized underground infrastructure. The project aims to develop flood control facility technologies that can protect citizens safety and property from urban flooding. In this paper, investigated the current status of underground infrastructure facilities introduced from overseas for the purpose of responding to urban flooding and examined the improvement effects through introduction.

As various accidents have occurred in underground spaces, we aim to improve the quality validation standards and methods as specified in the Regulations on Producing Integrated Map of Underground Spaces devised by the Ministry of Land, Infrastructure and Transport of the Republic of Korea for a high-quality integrated map of underground spaces. Specifically, we propose measures to improve the quality assurance of pipeline-type underground facilities, the so-called life lines given their importance for citizens’ daily activities and their highest risk of accident among the 16 types of underground facilities. After implementing quality validation software based on the developed quality validation standards, the adequacy of the validation standards was demonstrated by testing using data from two-dimensional water supply facilities in some areas of Busan, Korea. This paper has great significance in that it has laid the foundation for reducing the time and manpower required for data quality inspection and improving data quality reliability by improving current quality validation standards and developing technologies that can automatically extract errors through software.

도시가 발전하고 위생적이고 안전한 환경을 구축하기 위하여 지하 공간의 활용은 필수 불가결한 사항이다. 지하 공간의 개발이 진행될수록 시설물의 위치 관련 정보를 취득하고 관리하고자 다양한 기법이 적용되고 있으나, 현장에서 적용할 수 있는 정확한 정보는 부족한 실정이다. 본 연구에서는 이러한 지하시설물의 정보를 정확히 관리하고, 신뢰성에 기반한 현장 작업이 가능하도록 지하시설물 정보 품질 등급제의 세계적 현황을 조사하고 분석하였다. 연구 결과 정보 관리 선진국의 경우 지하시설물 정보에 대한 등급제를 통해 신뢰성에 기반한 관리가 이루어지고 있었으며, 이를 통해 활발한 현장 적용이 가능하였다.

본 연구에서는 KURT (KAERI 지하처분연구시설)를 포함한 지하연구시설에서 핵종 및 콜로이드 이동에 대 한 연구현황을 조사하였다. 화강암과 같은 결정질 암반층에 건설된 해외 지하연구시설들을 간략하게 소개하 고 비교하였다. 특히 Grimsel Test Site (GTS)와 ¨Asp¨o Hard Rock Laboratory에서의 핵종 및 콜로이드 이동연 구에 대한 주요 국제공동연구의 연구항목 및 내용, 진행중인 연구 프로젝트, 연구계획 등에 대해 조사하였다
