When a tunnel is excavated below groundwater table, the groundwater flows into the excavated wall of tunnel and seepage forces are acting on the tunnel wall. Such seepage forces significantly affect the ground reaction curve which is defined as the relationship between internal pressure and radial displacement of tunnel wall. In this paper, seepage forces arising from the ground water flow into a tunnel were estimated quantitatively. Magnitude of seepage forces was decided based on hydraulic gradient distribution around tunnel. Using these results, the theoretical solutions of ground reaction curve with consideration of seepage forces under steady-state flow were derived. A no-support condition and a supported condition with grouted bolts and shotcrete lining were considered, respectively. The theoretical solution derived in this study was validated by numerical analysis. The changes in the ground reaction curve according to various cover depths and groundwater table conditions were investigated. Based on the results, the application limit of theoretical solutions was suggested. 지하수위 아래에 터널이 굴착되면,지하수가 터널내로 유입되면서 터널 단면에 침투력이 작용하게 된다. 이 침투력은 내압과 터널 내공단면의 변위 관계로 정의되는 지반반응곡선에 큰 영향을 미치게 된다. 본 연구에서는 터널내로의 지하수 흐름으로 발생하는 침투력을 정량적으로 평가하였다. 침투력은 터널 주위의 동수경사의 분포를 바탕으로 계산되었으며, 이 결과를 바탕으로, 정상류 흐름일 때 침투력을 고려한 지반반응곡선의 이론해를 유도하였다.보강이 없는 경우와 전면 접착형 록볼트와 숏크리트 라이닝으로 보강된 경우의 변화가 고려되었다. 본 연구에서 유도된 이론해는 수치해석을 통해 검증되었으며, 다양한 토피고와 지하수위 조건에 따른 지반반응곡선의 변화가 연구되었다. 이를 바탕으로 이론해의 적용한계가 제시되었다.

신영진 ( Young-jin Shin ) 중앙대학교 국가정책연구소 2020 국가정책연구 Vol.34 No.2

현재 우리나라는 제4차 산업혁명의 핵심기술로 블록체인을 활용한 전자정부를 구현하고자 한다. 이와 관련하여 행정안전부가 발표한 ‘전자정부 10대 기술트렌드’ 중에 블록체인을 포함 하였으며, 지능형 정부로의 핵심사항으로 다루고 있다. 물론, 미국, 영국, 스위스, 스웨덴 등 일부 국가에서는 이미 금융, 의료, 부동산 등과 같은 행정분야에 블록체인을 도입하고 있으며, 우리나라에서도 중앙정부뿐만 아니라 지방자치단체 및 공공기관에서도 기존 행정서비스에 블록체인을 연계하고 있다. 따라서, 블록체인을 적용한 다양한 전자정부서비스가 구현되어야 하며, 이를 실현하기 위한 정책과제를 발굴하여야 한다. 본 연구에서는 블록체인 전자정부를 구현하기 위해 이용자를 대상으로 AHP기법을 적용한 설문조사를 통해 ‘전자정부 로드맵 31대 과제’에 대한 블록체인 전자정부의 실현가능성을 진단하고, 전자정부 서비스 및 정책에 관해 우선추진과제를 선정하였다. 이에 대해 블록체인 전자정부를 구현함에 있어서 대국민 서비스(74.07%)가 가장 중요하며, 전자적 국민참여 확대(53.70%)를 위한 전자정부과제가 가장 우선해야 한다고 보았다. 특히, 블록체인 전자정부의 우선추진과제에 대한 우선순위를 분석하였는데, 첫째, 정부차원에서는 정부의 법제도 정비, 기업의 기술투자 지원, 국민의 정책접근성 확대를 강조하였다. 둘째, 기업차원에서는 블록체인 전자정부를 위한 기술개발과 국민을 위한 서비스 컨텐츠 개발이 우선되어야 한다. 셋째, 국민차원에서는 블록체인 전자정부에 관한 전반적인 이해가 가장 필요하다. 이에 따라 전문가대상의 FGI를 통해 블록체인 전자정부 구현을 위한 종합적인 개선과제를 도출하였다. 즉, 법제도 측면에서는 법률 및 제도적 정비가 이루어져야 하며, 기술적 측면에서의 서비스 안전성을 강화하고, 관리적 측면에서의 종합적인 계획을 추진할 컨트롤타워의 설치가 추진되어야 한다. 이처럼 블록체인 전자정부가 추진된다면, 전자정부의 선도적 입지뿐만 아니라 국민을 우선 생각하는 정부모델을 실현할 수 있으리라 본다. At present, South Korea is trying to realize an e-government utilizing blockchain with the core technology of the 4th Industrial Revolution. In this connection, it includes the block chains in the “10 Electronic Technology Trends of the e-Government” announced by the Ministry of Public Safety and deals with important matters for intelligent government. Of course, some countries, such as the United States, the United Kingdom, Switzerland, and Sweden, have already introduced blockchains in the administrative fields of finance, medical care, real estate, etc. In South Korea, not only the central government, but also local government bodies and public institutions are linking blockchains to existing administrative services. Therefore, it is necessary to implement various e-government services that apply the blockchain and to find policy issues for realize the blockchain e-government. This study was conducted a questionnaire survey of users using the AHP method in order to diagnose the feasibility of the blockchain e-government of “e-government roadmap 31 major tasks” and to realize the blockchain e-government. As a result, service to the public (74.07%) was the most important factor in realizing blockchain e-government, and e-government tasks for expanding e-public participation (53.70%) should be given the highest priority. In particular, this study analyzed the priority of priority promotion issues of blockchain e-government. First, at the government level, it was emphasized the maintenance of the government's legal system, the support of technology investment by enterprises, and the expansion of public policy access for the people. Second, at the business level, it should be given to technological development for the blochchain e-government and to service and content development for the public. Third, at the people level, a general understanding of blockchain e-government is most needed. Accordingly, this study was derived a comprehensive improvement tasks to realize the blockchain e-government through FGI for experts. In other words, legal and institutional arrangements should be improved in the legal & institutional aspect, the service safety should be enhanced in the technical aspect, and the control tower should be promoted in administrative aspect. In this way, if blockchain e-government is promoted, it will be possible to realize not only the leading position of e-government but also a government model that gives priority to the people.

In the information and knowledge society, information and knowledge have become important media to improve national competitiveness. Improving the information and communication technology has brought out the various information invasions as well as information usages through broad information and knowledge. So a plan for national informatization should be involved in the ways to overcome local and national digital divides as well as information problems. The national informatization should develop through balanced international cooperation for IT utility based on information security. This study is for evaluating information security policies with information society adaptability model(ISAM) in 47 countries. An indicator of information security policy has three consistent categories: legal and institutional, physical and technical, and administrative information securities. Each indicator has increased by the values of experts in 47 countries. An indicator of national IT utility has three consistent categories: IT utilities by government, business, and the public. So two comparison factors have main-and sub-indicators. After it analyzed information society adaptability, the USA, Singapore, Canada were evaluated as high adaptable countries for informatization of 47 countries. Indonesia, Venezuela, Russia were evaluated as worst countries of them. As a case of South Korea was evaluated at 18th rank in 47 countries, so South Korea should rebuild a national policy for information security with participation of government, business, and the public for national balanced development of informatization.
